ChrUbuntu 12.04. Now with double the bits!

Update #4: There's a new version of the ChrUbuntu script that offers much more flexibility. Be sure to check out my latest post at ChrUbuntu: One Script to Rule them All!

Update #3: I've updated the script so that module loading works with beta and dev channel Chrome OS kernels. If you were on beta or dev channel and ChrUbuntu booted but you couldn't connect to WiFi/ethernet, try now. Thanks to not-so-lazy commenter "The Lazy Husband" for the pointer and fix. I've also added a possible fix for some people getting out of space errors. The script below now works with external USB Flash and SD Card ChrUbuntu installs.

Update #2: Instructions for installing to an external USB or SD Card are up!


Update: The script now works on older Cr-48 and Samsung Series 5 Chromebooks. For details, see this blog post.

I'm excited to announce the release of ChrUbuntu 12.04! ChrUbuntu is a clean install of Ubuntu 12.04, the latest Long Term Service release customized to run on Chromebooks. This is the first Ubuntu for Chromebooks that is 64-bit which means it will be twice as fast! Okay, maybe not but it'll at least be compatible with the new Chromebook and Chromebox :-) Also with this release, Chromebook features like 2-finger scrolling and audio and brightness controls work out of box.

Installing ChrUbuntu is extremely easy, just follow the steps below. Want to say thank you for ChrUbuntu? Feel free to do so in the comments below or show your support by visiting the advertisements on this blog. If you purchase a Chromebook or any other Amazon items using the links on the right, I get a small portion of the cost :-)
  1. To get started, make sure your Chromebook is in developer mode and has a developer BIOS installed. See Google's instructions for the Cr-48, Samsung Series 5, the Acer AC700, or the 2nd generation Samsung Series 5 550 and Chromebox Series 3 depending on your model. Samsung and Acer owners should pay special attention to the Developer BIOS instructions.
  2. Reboot your Chromebook but do not login. Make sure you have a WiFi or Ethernet connection at this point. 3G is not recommended. Press CTRL+ALT+=> (=> is the forward arrow where the F2 key would be on a PC). Do not use the normal CTRL+ALT+T method to get a shell. Use the CTRL+ALT+=> method while no one is logged in.
  3. Login as user chronos, no password is needed.
  4. As the chronos user, run:

    wget http://goo.gl/tnyga; sudo bash tnyga

    Make sure you have the command exactly right. tnyga is all lowercase letters and would sound like "tee in why gee aye" if you said it out loud (go ahead, try it!). If you get a "not found" error, make sure you have Internet connectivity.
  5. You'll be prompted with some information about your Chromebook. You may need to run an additional command to install a developer BIOS on your Chromebook or, if you have a 1st generation Chromebook, you might be notified that a special non-official kernel will be used to allow 64-bit Ubuntu to run on your hardware. Press Enter to continue.
  6. The Chrome OS stateful partition where your data and settings are stored is just short of 11gb by default, the script shrinks the stateful partition to make room for ChrUbuntu. You can choose to give ChrUbuntu from 5gb up to 10gb in 1gb increments (Note: If you've installed a larger SSD in your Chrome device, your max number and recommended max will be larger). I recommend not going higher than 9 as 10 leaves Chrome OS with very little free space (less than 1gb). Once you've entered a number, your hard drive will be repartitioned. It may look like the Chromebook is doing nothing for 10-15 minutes but let it be, after awhile it will reboot and re-initialize the stateful partition. This process takes about 5 minutes and then the Chromebook reboots again and shows you the Welcome screen you got when you first turned on your Chromebook out of the cardboard box.
  7. Go through the Chrome OS setup process again until you get to the Google login page. You'll need to have a WiFi or Ethernet connection again at this point. 3G is not recommended. Now follow steps 3 through 5 again. This time the script will see that you've already made room for Ubuntu and will start downloading the ChrUbuntu image and copying it to the SSD.
  8. There are 52 100mb files to be downloaded. Each is compressed so the actual download size ranges from less than 1mb in size to 90mb in size. The total size of all the files is about 1gb compressed and 5gb uncompressed so the download and install will take awhile. The files are named ubuntu-1204.binXX.bz2 (where XX is aa, ab, ac, ad, ae, af... ba, bb, bc... all the way to bz). If you want to see how big each piece is, take a look here.
  9. The script keeps track of which of the 52 files have been successfully installed so if you lose Internet connectivity, or the battery dies (you should be plugged in BTW), etc, just re-run Step 8 and it should resume where it left off.
  10. After all 52 files have been downloaded and copied to the SSD, the script will make a few more updates to your Cr-48 and then reboot.
  11. You'll see ChrUbuntu start up! The username is "user" and the password is "user" if you need to make changes.
  12. Right now, you're in ChrUbuntu but if you reboot, you'll be back in Chrome OS. To make ChrUbuntu the default, run:

    sudo cgpt add -i 6 -P 5 -S 1 /dev/sda

    (password is "user"). It should be possible to run this from ChrUbuntu or Chrome OS.
  13. To make Chrome OS the default again, either turn off Developer Mode, or run:

    sudo cgpt add -i 6 -P 0 -S 1 /dev/sda

  1. Thanks Jay! Awesome!

    Does turning off Dev mode erase Ubuntu or just make it unavailable? For example if I went off Dev mode and then switched back to Dev mode, Ubuntu would still be able to boot?

    ReplyDelete
  2. @spartahawk: it makes ChrUbuntu unavailable as the secure boot process will refuse to boot from the unofficial partitions. Note that that on the Samsung and Acer you might need to flash back to the normal (non-dev) BIOS with:

    chromeos-firmwareupdate --mode tonormal

    before going back to normal, non-dev mode with the switch.

    Worst case scenario, USB Recovery should ALWAYS restore the Chromebook to 100% official Google bits :-)

    1. You may or may not want to mention this, and perhaps it's just obvious anyway: If your script has been used in the past and the SSD is already partitioned accordingly, it just goes ahead and starts downloading the 52 100mb files. It is doing that right now for me, and I'm guessing I won't be repeating steps 3 through 5.

      Delete
    2. This is the case for me. I used an older method, which didn't have such an easy partitioning option, to install 10.04 on my cr48.
      Is there a method to force the partitioning part of the script?
      Would a full recovery/reinstall do the trick?

      Delete
    3. Yeah I'm sure that doing a USB restore before running the older or this latest script would make everything happen as Jay has described in this post. But hey I liked it. I was much faster and all kind of done in a single step, and the install seemed to proceed and complete perfectly.

    4. Hello spartahawk and John McNulty, I need to clear the point, I install Ubuntu 12.04, It works fine, now I have the switch (hardware) on dev mode.

      what exactly meant that: sudo cgpt add -i 6 -P 5 -S 1 /dev/sda ?

      I should to run this with switch on dev mode? or how?

      Actually when chrome book start appear light blue sad computer, this screen never disappear?

      If I use Ubuntu switch (hardware) always should to be in dev mode?
      Please help.

  3. Thanks for the guide. I just got my series 5 chromebook yesterday (I know right? So late the party!) and installed 11.04 via your guides but I was upset that I would have to use old versions of Ubuntu but then here you come with this guide.

    Things seem to be running well after installing gnome3 (gnome > unity imo), and the wifi dropping issues I was having seem to be gone with this update.

    Thanks for the guide and script.

    8. It seems like the google developers have made an announcement that they have reverted all 64-bit builds back to 32-bit. I think it was because of fewer driver support.

      https://groups.google.com/a/chromium.org/group/chromium-os-dev/browse_thread/thread/48f9171bb3d878dd

      Basically, use the old 11.10 script, which installs 32-bit Ubuntu. The 12.04 script no longer works since it installs 64-bit Ubuntu, and needs a 64-bit kernel.

      Somebody tell the scriptmaker.

    9. I’m posting this multiple times because there are a few different threads asking about it. Also I go into more detail on my blog http://jamesdressel.com/?p=94 but here is how I fixed this problem.

      I used this recovery image https://dl.google.com/dl/edgedl/chromeos/recovery/chromeos_1660.143.0_x86-mario_recovery_stable-channel_mp-v2.bin.zip and then I downloaded all of the 52 files for the 11.04 script , and ran it. Then I did two system updates (11.10 and 12.04)

      Delete
  6. Thanks Jay. I was considering going from 11.10 and upgrading the whole way...my poor cr48 couldn't handle it though.

    To build on the post someone made above, Gnome 3 is very usable, and it's what I use on my 'main' daily use computer. Once you use it for awhile the workflow is much better than unity/aero/insert your ui here.

    2. Nevermind. I figured this out. If you want to install Gnome 3 (and it does work surprisingly well on an older cr48 unit) then this guide may be of use. --> http://www.filiwiese.com/installing-gnome-on-ubuntu-12-04-precise-pangolin/

      It suggests status-monitor shell extension for an addon but if you install it make sure you install package gir1.2-gtop-2.0 first from the ubuntu repos otherwise you will get an error. Took me a few minutes to realize that I needed something else first.

  7. Is this recommended over update manager?

    ReplyDelete
    Replies
    1. This will wipe out your existing ubuntu data so if you are looking to start fresh this may work out better for you. Update manager will upgrade your existing install however. The main advantage to using this and starting over is that it also marks a switchover from using a 32-bit kernel to a 64-bit one which will provide some performance benefits. I will say that it does run a bit snappier now.

      Delete
  8. To make switching easier, do this

    Go into the Home folder in Ubuntu and press "Control + h" together. Click the file named .bashrc
    Edit the .bashrc file, and add this to the end of the file:
    alias chromeos='sudo cgpt add -i 6 -P 0 -S 1 /dev/sda;echo "Switched to Chrome OS, restart the machine to take effect"'
    Go to your terminal, and type in chromeos. You will be switched to Chrome OS when you restart.

    In Chrome OS, press Ctrl+Alt+F2 to open bash, login as chronos. Inside Chrome OS press Ctrl + Alt + =>.
    Type in chronos, then sudo su, then
    qemacs .profile
    Now type in
    alias ubuntu='sudo cgpt add -i 2 -P 0 -S 0 /dev/sda;sudo cgpt add -i 6 -P 5 -S 1 /dev/sda;echo "Switched to Ubuntu, restart the machine to take effect"'
    Now to save the file press Control + x + s until it says it did it. Then press Control + x + c until you go back in terminal.
    In terminal type Ubuntu and you should be in Ubuntu, if not do Part 2 again.
    Congrats, now you can type Chromos to go to Chrome, Ubuntu to go to Ubuntu.

    1. Oh and BTW, under Chrome OS, its vi .profile and to save press ctrl+c then type :save .profile then to exit, type :quit

  9. Thanks Jay -- I had just dedicated an overnight to having the little chromebook update itself to 12.04, this makes it much saner. Now I'm just going to re-install anyways, since this is 64-bit ;-). Would you care to explain/help how your building these images (beyond the chromium wiki page).

    2. WEP/WPA/WPA2 are encrypted WiFi connections. The script doesn't care what kind of connection you have as long as it can download the files. You could in theory install over 3G although it'd take forever, be considerably more flaky and burn your bandwidth quota up :-)

  16. Ok, for those of you having problems getting "wget http://goo.gl/oyjlt; sudo sh oyjlt" to work properly, here is how I resolved it.

    First, I split the command into 2 parts:

    Part 1 -> wget http://goo.gl/oyjlt <-This will download "oyjlt". Once this is done, run...

    Part 2 -> sudo sh oyjlt.X <-If you have tried running the full script, oyjlt maybe saved with a number attached (IE: oyjlt.1). Watch for that after running part 1.

    Part 2 will start the actual download and install process.

    I hope this helps.

  25. Noob error/question:

    I followed the instructions and properly installed Ubuntu. While booted into Ubuntu I ran [sudo cgpt add -i 6 -P 0 -S 1 /dev/sda] to make Chrome OS default. It worked and while in Chrome OS I ran the other command to make Ubuntu default but it didn't seem to work.

    I tried and tried again but no luck. In my tired and sleepy state I ran the install script again thinking it would fix the issue. But I stoped the script by pulling the battery. After a few boot loops Chrome OS started up again and I tried the command to make Ubuntu default again but this time it just sat in some random boot process.

    I pulled the battery again and then just toggled the developer switch. It began the repartioned process again so I'm guessing it erased Ubuntu.

    So my question is, do I have to install Ubuntu again? Or is there any way to salvage the Ubuntu install?

    Thanks for any help.

      Part 2: sudo sh oyjlt.x <- only replace the .x with a number (IE oyjlt.1) if the file has one; otherwise, don't use the *.x portion.

      This was the only method I could get to work. Hope this helps.

    1. I am getting the exact same error. I see below you got it fixed. You just went back and forth between dev and normal and rerunning the script? It eventually worked? with no new steps?

      Delete
    2. I just pushed the power button until it stopped retrying and did it over again...
      What struck me was that obviously it has nothing to do with the internet connection, as the script is downloading the same file all over. It must have something to do with the missing hash sum value.

      Delete
  33. Now I went through the process again, going back and forth to normal and dev mode, and the download process took me to binbi.bz2 this time, where I ultimately receive the error again. The file is actually saved and written to stdout, but it seems to me that this is just a check sum error where the computed check sum cannot be validated because there is no stored one to compare it with. If that is correct, would there be any way to skip the check sum function?

  46. The script should detect the size of the harddrive rather than assuming the size. I have a 80GB SSD in my cr48 and had to modify the script, change "10" to "100" in the size selection to allow for ubuntu to have the majority of space.

  49. Just want to say thanks to Jay Lee again, so thank you SO much! I had bought my chromebook right when it hit the shelves, believing there would soon (or at least sometime) be Google made alternatives for the likes of FileZilla, Notepad++ or even Gimp and Thunderbird. So that obviously did not happen, and in the end I did not use the chromebook at all. Although I like the keyboard, it is just not convenient enough for casual surfing, as I have a tablet for that. But now, I have it in everyday use again and really like it!

    ReplyDelete

  54. Nice work Jay, this looks pretty great on my CR48 and I'm very much liking it.

    However, I'm having a couple issues, and wondering if you have anything you can point me to.

    On one hand I'm having a little bit of a problem with the missing keyboard keys and replacing them (http://redd.it/tts4i), but that's not really my main issue.

    The biggest problem for me right now is the disappearance of the broadband device (wwan0) since I ran all the updates after the first install. At least, I'm pretty sure that was the point where it stopped working. I was able to connect to Verizon once before, but it does not show under network settings in the upper right, nor does it show in ifconfig. Nor after rebooting. Is this a driver issue, or is there something I should be able to do to reenable or initialize the device?

    Thanks.

    ReplyDelete
    Replies
    1. So I've seen the notes people have taken on the issue with the mobile broadband radio, and I've gotten it to work again by booting to ChromeOS first from a hard-power, then soft-rebooting to Ubuntu... but it still goes away the first time you so much as suspend the machine.

      If you (or anyone else!) has any insight as to where I can keep tabs on any progress in fixing this, I will be very grateful. It is pretty much the only thing that is keeping me from switching over to Ubuntu ENTIRELY as I use 3G quite a bit on this laptop.

      Delete
  55. Thanks to Jay. I installed it over 11.04 in my cr-48 last night. Works great.

    I've been using three-finger click/tap as middle mouse click, but by default this 12.04 does not enable three-finger tap/click. Just found a way to enable it with synclient:
    * to show current settings:
    synclient -l
    * to set 3-finger tap as middle click:
    synclient TapButton3=2
    * to set 3-finger click(hard click):
    synclient ClickFinger3=2
    * to set 2-finger tap as right click:
    synclient TapButton2=3

    You can see many interesting settings like "RightTopButton" as middle click with synclient -l

  83. Thanks again for this really cool operating system, I am enjoying it and can report that LXDE works great (with some tweaking needed for the brightness and sound buttons; easy if you modify the lxde-rc.xml file in /home/user/.config/openbox/).

    Any idea what file system of /dev/sda6 is? It just shows up as "unknown" in gparted as the partition separating the chrubuntu partition from the stateful partition, which has all the 2 GB of free space left that I now want to get my hands on; until gparted can identify that in-between partition it refuses to move it, and in the mean time I find myself wanting that extra space to play around in. (I debated between 8 and 9 GB and unfortunately picked the lower number.)

    Or any other way to (safely) move that unknown partition once I shrink the stateful partition? Anyone? I have always used gparted but am open to other options. Thanks.

  85. It works on my Chromebox too. But my USB-serial rs232 adapter does not work.

    The adapter works in a standard Ubuntu in a regular PC and gives me the interface "/dev/ttyUSB0".

    Bus 002 Device 003: ID 4348:5523 WinChipHead USB->RS 232 adapter with Prolifec PL 2303 chipset

    I also tried:
    sudo modprobe usbserial vendor=0x4348 product=0x5523
    which did not show any error, but still did nothing.

    From commands "locate pl2303" and "locate usbserial" I saw all the required kernel modules were in the system.

    2. James, thanks for your contribution. 1 question, does updating from 11.04 to 12.04 result in 32 bit Ubuntu in the end?

      Also,this release of Ubuntu 12.04 comes with brightness and volume controls out of the box, will going through your method have this as well? If not, how did you find drivers for your chromebook keyboard? Thanks!

      Delete
    3. Yes, these instructions leave you with 32 bit. If you want 64 bit your best bet IMHO is to flash your BIOS, and do a USB install of ubuntu.

      The buttons did not work out of the box (I haven't bothered to change them) they are maped to the F-keys.

Maybe a 32bit script version?

      I used the recovery image that you have provided, but my Cr-48 is giving me stuff about it not being recognized/too old (can't recall exactly what it said). Point being: it didn't work as I had hoped.

  96. I installed 11.04 from the older script and upgraded twice to get to 12.04 which is working fine. However, I made the mistake of ticking the install grub2 on /dev/sda box on the way and can't boot to chromeos since I can't persuade the grub menu to appear with any of the usual recipes. Has anyone with this setup got a working boot menu?

  97. Hmm, after restoring chromeos from usb and starting again
    with an 11.04 install then ->11.10 upgrade in Ubuntu I am still booting straight into Ubuntu when I reboot.

    Chromeos/Ubuntu was dual booting OK with the original 11.04 install before the upgrade and no "install grub" boxes were ticked this time during the upgrade.

    I guess the question should really be: -

    how do I get a chromeos boot option back after an Ubuntu update?

  98. I try to boot ubuntu, but with no luck. I see with parted, that the ext4 partition i partition 7. I change cgpt add -i 6 -P 5 -S 1 /dev/sda to cgpt add -i 6 -P 7 -S 1 /dev/sda but still no boot in ubuntu. Any idea?

  99. It's odd I had Ubuntu running fine, then switched back to Chrome OS, and now it will not boot Ubuntu. While I was back on Chrome OS it did update did that reformat the drive back to it's original state? Thanks for the help.

  104. Hi folks,

    Is it possible to install Ubuntu *NOT* directly over the internet?

    My internet connection is terrible! I'd like to download Ubuntu onto a USB via my college connection, and then install Ubuntu on my Chromebox through the USB. Is this possible?

    Thanks!

  105. Everything went smoothly, but I can't get wireless to work reliably. Sometimes it connects, but then it drops the connection fairly quickly. I tried turning off power management and hardware-based encryption (per various guides out there), but to no avail. Any suggestions? Thanks!

  106. Would it work to restore to an old 64 bit ChromeOS from USB and then update it and install this? Do 64 bit ChromeOS recovery images exist for series 5?

    1. Ok figured I could give a bit more info so here are some commands I thought would be helpful. I found an UbuntuForums post with a similar problem but it was and acer laptop and the poster was having issue with their settings saying that *-network DISABLED unlike mine which says *-network UNCLAIMED. Sorry I couldn't get a screenshot but it appears that I get a "vfat" error when using a USB memory stick. Lastly I don't have a usb to ethernet adapter to test if ethernet works.

      Thanks

      $ iwconfig

      lo no wireless extensions

    2. What does a 'lsmod | grep ath' show?

  109. I followed the instructions to a tee, but have been unable to get Ubuntu to boot. After step 10, my CR 48 reboots back into Chrome OS. I've tried starting over with a fresh recovery, and tried rerunning the script several times. After it boots back into Chrome, I rerun the script and it downloads about a third of the files again, but I still get the same results every time.

    I've even tried running the following script at the end, thinking it installed properly, but it's just not booting into ChrUbuntu.

    Please let me know what is wrong, and how I can fix it.

    1. This set of instructions might help you pinpoint what went wrong:

    2. @ObjectiveTruth: try running thru the instructions again now. Pay close attention to the fact that the script command is now "sudo bash kxf3n" instead of just "sudo sh kxf3n". I believe your issue was that the limited standard shell was being used instead of the richer Bash shell and that was causing errors with the script.

      Delete
    3. I've been having the same problem. Re-downloading the files right now (for probably the fourth time now lol) and will try using bash instead of sh.

      Thanks so much Jay! :D

    4. ..just finished and everything is working PERFECTLY so far (using bash vs sh) on my Cr48 (Mario Pony) w/ 64 GB SSD.

      Thanks again!

  110. I don't actually know what I'm talking about, but it sounds like the partitioning went fine, but that you didn't get your BIOS setup correctly to boot the other kernel. I have a Samsung, and for me, I had to execute some command to tell the BIOS that it's okay to boot other kernels.

  111. Such an awesome article. My cr-48 was sitting in a closet until I read this. Thank you. I do have one question. I only allotted 6 gigs to the Unbuntu installation. How can I increase it now? Thank you. ~Josh

  112. No idea, but can you give me a mini-review of Chrubuntu? Is it faster than regular Ubuntu? Is it even worth installing? Did you have any issues?

    ReplyDelete
  113. Thank you kind sir for this delightful script.

    I'm actually going to try ditching my windows laptop at work and using the s 5 550 as a DD for awhile. Probably will be in Ubuntu most of the time, however thanks to you Mr. Lee it will be quite stable and super fast with the SSD.

    Best Regards

  114. I fixed my wireless problems by following these instructions (http://chromeos-cr48.blogspot.com/2012/04/chrubuntu-1204-now-with-double-bits.html?). Basically, start with the 11.04 version and then upgrade to 12.04. I'm using a gray Samsung.

  115. Im concerned about memory.. assuming I ONLY want to use Ubuntu, can I give it 12 or even 14 GB instead of 10? If i give it 10, after the entire installation proces, how much actual free space will there be? Would I be able to install Java and Eclipse and still have a few gigs left over?

  116. Hi, I try to run your script on my Chromebox that I get from the Google IO. Everything works well until I have finish installing Ubuntu. However, it just gives me a black screen when done with installation and cannot log into Ubuntu. I try running the script multiple times and I try different version of your script and none of them works. Also every time I re-run the script, it will download some of those files due to a fail md5 check. Do you by any chance know what might be the cause?

    I am using DVI to connect to my monitor and I try DP++ and doesn't make a difference.

  117. Hi. I want to modify the script to install any ubuntu version i want. But i have one question. The image files you have hosted, instead of them can i use plain .iso file?
    I tried that, but it wasn't making any progress in installation. Please let me guide in the direction of using an .iso file for installation. ( take linux mint for example. )
