Crouton: Installation issues, Mount errors even after chrome powerwash.

[Ltbattlebadger]

Please paste the output of the following command here: chronos@localhost / $ sudo edit-chroot -all
name: precise
encrypted: no
Entering /mnt/stateful_partition/crouton/chroots/precise...
mount: /run/crouton/mnt/stateful_partition/crouton/chroots/precise/sys/fs/selinux not mounted or bad option

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

Please describe your issue:

This is my first time doing something like this so please excuse me if I miss some piece of information that I am supposed to post here. Also posting before I leave for work so any immediate responses this morning will be delayed.

I was able to install everything just fine on the first run yesterday and installed Unity using Crouton. However, I got really confused trying to get the crouton extension to work. After getting frustrated I ended up putting any little snippet of code into both the chrome side terminal as well as the ubuntu side terminal and things just got weird so I tried to delete the chroot and do a fresh install the correct way the first time. Well, ever since then, I get a mount error when try to an install. I got the same error after a powerwash this morning.

mount: /run/crouton/mnt/stateful_partition/crouton/chroots/precise/sys/fs/selinux not mounted or bad option

   In some cases useful info is found in syslog - try
   dmesg | tail or so.

If known, describe the steps to reproduce the issue:

@Ltbattlebadger,

Since your croutonversion command didn't get executed, we don't have a lot of the details we need to troubleshoot your issue yet.

Do you by chance have one of the three Chromebooks that have Android apps (Pixel 2, Asus Chromebook Flip, Acer R11) on the beta or dev channel?

You may need to update your chroot to get the latest crouton changes for Chrome OS and SELinux, you can do that using something like:

sudo sh ~/Downloads/crouton -n precise -u

You also may be running into issue https://github.com/dnschneid/crouton/issues/2706 if Google Play is crashing. See issue https://github.com/dnschneid/crouton/issues/2706#issuecomment-241812246 for a possible temporary fix.

@Ltbattlebadger,

This is happening on mine too now when doing a crouton update but the changes in https://github.com/dnschneid/crouton/issues/2706#issuecomment-241812246 fixed it.

FINALLY SOMEONE WITH THE SAME ISSUE!!!
This is the error I get when trying to launch the chroot environment:
launching Kali Linux...
Entering /media/removable/sd/chroots/kali-rolling...
mount: /run/crouton/media/removable/sd/chroots/kali-rolling/sys/fs/selinux not mounted or bad option

   In some cases useful info is found in syslog - try
   dmesg | tail or so.

I'm on the Dev channel for updates:
Version 54.0.2837.0 dev
Platform 8737.1.0 (Official Build) dev-channel veyron_speedy
Firmware Google_Veyron_Speedy.6588.197.0

After the last system update this started happening. I tried to Google around to find a solution and I
even tried to use an older sd card with a previouse installation of the chroot environment just to verify it was
not my chroot environment. I also noticed that I can't enter the chroot, I can't use xiwi to pull single apps out,
I can't update chroot, nothing. The error recommended looking at dmesg but I could find anything in there that
stood out.

dmesg output:

I am using the newest Toshiba Chromebook 2. I updated my chroot using the command you supplied. At the end of that script running, it gave me this:

Pruning /mnt/stateful_partition/crouton/chroots/precise mounts...
mount: /run/crouton/mnt/stateful_partition/crouton/chroots/precise/sys/fs/selinux not mounted or bad option

   In some cases useful info is found in syslog - try
   dmesg | tail or so.

Unmounting /mnt/stateful_partition/crouton/chroots/precise...

I looked at the comment #2706 and I have no idea how to begin doing that.

[DennisLfromGA]

@Ltbattlebadger,

I updated my chroot using the command you supplied.

Sorry, the enter-chroot script needs to be edited per https://github.com/dnschneid/crouton/issues/2706#issuecomment-241812246.
If you're not comfortable with editing the script, you may have to wait until pull request https://github.com/dnschneid/crouton/pull/2735 is approved and merged, sorry.

Hello,
I have same issue on Lenovo N22 :(

Installation: https://paste.ee/p/h11A4

Starting ( sudo enter-chroot startxfce4 ) : https://paste.ee/p/RaMIP

Tried even sudo sh ~/Downloads/crouton -n precise -u and result is same: https://paste.ee/p/9unXt

Dmesg: https://paste.ee/p/xNuRO

[trance1975t]

Same issue, Acer Chromebook 14. Seems to have happened after the most recent Chrome developer channel update.

[DennisLfromGA]

Same issue, same temporary solution: https://github.com/dnschneid/crouton/issues/2706#issuecomment-241812246

[BKPepe]

I'm newbie with it, please can you tell me what to do next?

I saved it, did exit, then shell and tried sudo sh ~/Downloads/crouton -t xfce (so I edited file again, then tried sudo enter-chroot startxfce4 result is same)
tried also -n precise -u and same still warning and still nothing :(

Still its saying:
/mnt/stateful_partition/crouton/chroots/precise doesn't appear to be a valid chroot.

[DennisLfromGA]

@BKPepe,

I saved it, did exit, then shell and tried sudo sh ~/Downloads/crouton -t xfce (so I edited file again, then tried sudo enter-chroot startxfce4 result is same)

The command you used will install a brand new 'precise' chroot with an new enter-chroot script that doesn't have your changes.
[ I think you'd be better off installing 'trusty' with: sudo sh ~/Downloads/crouton-r trusty -t xfce ]

tried also -n precise -u and same still warning and still nothing :(

When either of those fail, you can re-modify /usr/local/bin/enter-chroot and then run it without any command-line options, like: sudo enter-chroot

This will hopefully prompt you with _'Would you like to finish the setup? [Y/n/d] '_
Now press 'enter' or enter Y and let it finish.
Once it finishes successfully, you'll be able to run your desktop gui, using: sudo startxfce4

Hope this helps,
-DennisL

[BKPepe]

Did it, but without success. Maybe its wrong to run: sudo vim ?

http://paste.ee/p/C0Dv8

Full log what I did is here: http://paste.ee/p/6QFoS

Still dont know, why it doesnt work

Since yesterday I am on irc channel crouton on freenode

[Ltbattlebadger]

@DennisLfromGA

I am comfortable trying to edit the script. However what I am unsure about is it a physical file that I am editing on my chromebook? Would that be the crouton file I downloaded and what program do I use to open that up and edit it. or do I edit a command when I type it into shell?

[DennisLfromGA]

@BKPepe,

The chroot setup script may be broken. Your chroot is not fully configured.
Removing the chroot setup script. You may want to update your chroot again.

So, _'You may want to update your chroot again.'_ may be what you need to do at this point.
When it fails, try running your modified enter-chroot script again.

If that doesn't work, there's another way to extract crouton on your Chromebook, modify enter-chroot, and run the main.sh script. That will require many more directions that I would prefer to avoid if at all possible.

Now it says this: http://paste.ee/p/Q6Zzi

@BKPepe,

So, you haven't modified the file yet? If not, you'll get 'mount' error above every time.

The file you need to modify is /usr/local/bin/enter-chroot on your Chromebook.
The modifications are explained in https://github.com/dnschneid/crouton/issues/2706#issuecomment-241812246

I use vi (vim) to edit files, it has a bit of a learning curve for the uninitiated but it's powerful.
I noticed you were trying to get 'nano' here but that's now a dead link.

-DennisL

[BKPepe]

I have modified file as you can see it says unmount isnt possible.
edit-chroot, are you sure? In #2706 it says enter-chroot

I use vim as you can see. I liked nano or pspad if its possible

[DennisLfromGA]

@BKPepe,

edit-chroot, are you sure? In #2706 it says enter-chroot

You're right, I mistakenly said edit-chroot instead of enter-chroot, I fixed it now - sorry.

I looked at your output above and the failure may now be due to the error thrown when trying to umount selinux. I would suggest editing an un-modified /usr/local/bin/enter-chroot script as follows:
( I'm using sed so there's no need to use vi )

cd /usr/local/bin
sudo sed -i.orig 's:mount -o remount,ro "$CHROOT/sys/fs/selinux":umount $CHROOT/sys/fs/selinux || true:' enter-chroot

That should modify the file and make a copy of the original named enter-chroot.orig for safe keeping.
Then try running sudo enter-chroot again and see if it works.

-DennisL

[BKPepe]

Wohoo, finally its working. Awesome job, man.
Thanks

[BKPepe]

Kinda reminder that I have Lenovo N22, but on Ubuntu - Trusty
Keyboard work, external mouse work, but touchpad isnt :(

(trusty)jana@localhost:~$ uname -a
Linux localhost 3.18.0-12913-g0be86ca #1 SMP PREEMPT Thu Aug 25 01:07:11 PDT 2016 x86_64 x86_64 x86_64 GNU/Linux

[tanjinjack]

It appears that the fix (editing enter-chroot) only works for the xfce interface. I tried it several times with kde but only trying with xfce would the installation continues.

[DennisLfromGA]

@tanjinjack - Try this simple fix instead and see if it works on a broader scale: https://github.com/dnschneid/crouton/pull/2748/commits/fe9dad6b3d569c1a97411aa7318582dc8c31b27a

How do you edit the file?? in the terminal? can someone explain how?? I have this same problem.

[choas0422]

I've been putting the sd card in a seperate linux pc to make the changes.
Seems to be the easiest way without using vim...

RESOLVED - I have done the -DennisL sed thing, and I am now back up and running... (Thanks Dennis).
... so what is the next step?
Do I update the crouton file as normal and update everything? (I'm running trusty).
sudo enter-chroot -n trusty -b xiwi -T startxfce4

Version 54.0.2840.24 beta (64-bit)
Platform 8743.25.0 (Official Build) beta-channel auron_yuna
Firmware Google_Auron_yuna.6301.59.8

Update: Downloaded from within trusty, chroot terminal, rebooted, updated all working :-)

Thanks for all the help, these Issue pages are a great resource.
Cheers.

[DennisLfromGA]

@SilverWave,

I have done the -DennisL sed thing, and I am now back up and running... (Thanks Dennis).

That should not be necessary any longer since PR https://github.com/dnschneid/crouton/pull/2748 has been merged.

... so what is the next step?
Do I update the crouton file as normal and update everything? (I'm running trusty).

Since you're a little late to the party ;), we don't know what you're working with/on and what you've done/not done. But you can hardly go wrong by updating your chroot. You can do that for a 'trusty' chroot using something like:

sudo sh ~/Downloads/crouton -n trusty -u

sudo enter-chroot -n trusty -b xiwi -T startxfce4

The command string you show above would just drop you into your xfce4 desktop and not perform any updates. If you just want to get into your desktop, you can do it a little easier with the following:

sudo startxfce4 -n trusty -bX xiwi-tab

_Hope this helps,_
-DennisL
