Crouton: Trying to copy a chroot from one USB to bigger USB

[thunderbunker]

I have installed a chroot running xenial onto a 32GB USB drive. I want to clone that to a bigger 256GB USB drive. They are both formatted to Ext-4. When I clone it using this in crosh:

sudo edit-chroot -C ~/media/removable/my_new_drive_name xenial

I get "Chroots can only be copied to ext filesystems." I know they are both formatted to Ext-4, am I doing the wrong command? My model is the Samsung Chromebook 3.

Any help is appreciated.

@thunderbunker,

Your syntax includes the tilde character '~' which pins it to start in your $HOME folder that is encrypted (ecryptfs) so maybe that is all that's wrong with the command. Simply remove the tilde from the beginning of the path you specify like this:

sudo edit-chroot -C/media/removable/my_new_drive_name/xenial

However, if you are copying from external media then you'll need to use the -c option to specify where to find your chroots. Use something like this -

sudo edit-chroot -c/media/removable/my_old_drive_name/chroots -C /media/removable/my_new_drive_name/xenial

The routine that the checks the file system is linked here and shown below -

# Don't allow copying to non-ext filesystems (but don't check if in same directory)
if [ -n "$COPY" -a "${COPY#*/}" != "$COPY" ] && \
        df -T "`getmountpoint "$COPY"`" | awk '$2~"^ext"{exit 1}'; then
    error 2 "Chroots can only be copied to ext filesystems."
fi

The actual copy routine is linked here.

The check uses df -T on the path you gave it after the -C so you could run it manually to see what is returned, here's what mine shows for a mounted USB stick I named '32GB.EXT4' -

chronos@localhost ~ $ df -T /media/removable/32GB.EXT4/
Filesystem     Type 1K-blocks  Used Available Use% Mounted on
/dev/sdb       ext4  31074284 45052  29427696   1% /media/removable/32GB.EXT4

So it recognizes mine as an ext4 file system.

If you first 'cd' into the location you want it copied to and then specify that path, I think the 'check' will be bypassed according to the comment in the check routine. Something like this might work -

cd /media/removable/my_new_drive_name/chroots
sudo edit-chroot -c /media/removable/my_old_drive_name/chroots -C ./ xenial`

One other option is to first backup your chroot to ~/Downloads and then restore it to your new destination.

Hope this helps,

Thank you for your quick reply. However, since I am copying from an external drive I used the second command:
sudo edit-chroot -c /media/removable/Ext4/chroots -C /media/removable/Mapoo xenial

The output was:
Unmounting /media/removable/Ext4/chroots/xenial... /media/removable/Mapoo already exists

What does this mean?

Thank you.

@thunderbunker,

The output was:
Unmounting /media/removable/Ext4/chroots/xenial... /media/removable/Mapoo already exists

What does this mean?

I'm not sure, it may be simply because you didn't use the '/' character at the end of the DEST directory as specified in the usage -

DEST can be a directory, in which case it must end in a slash.

I'm sorry I didn't include the '/' ending in my examples above but I've since corrected them.

But you also need to give it the full path to the destination chroots directory, something like:

sudo edit-chroot -c /media/removable/Ext4/chroots -C /media/removable/Mapoo/chroots/ xenial

Hope this helps,

[thunderbunker]

@DennisLfromGA

It is copying right now. Thank you for your help!

[thunderbunker]

Shoot, I came back after 20 minutes and this happened:

As I can see: I download such applications like minecraft and steam.

What happened?

[DennisLfromGA]

@thunderbunker,

Sorry, I don't know why it started to error out.
Sometimes a space or other special characters have to be escaped '\' out of the command but it doesn't look like that's the case here.

You could reboot and try again or just use the backup / restore routine I mentioned earlier.
That way you'd also have a fresh backup of your chroot - two birds... ;-)

Hope this helps,
-DennisL

[thunderbunker]

It's actually copied a little differently. However, I can't find the command to run the chroot. The command for the old one was

sudo sh '/media/removable/Ext4/bin/startunity'

I've noticed that the bin folder is under chroots/xenial

That command doesn't work. Strange.

The problem is that I cannot back up the chroot because it is 30 GB. My disk space is only 12 GB max.

How can I run it?

Thanks.

[thunderbunker]

Apparently I found the command:

sudo enter-chroot -c /media/removable/Mapoo/chroots xenial

The output was:

Entering /media/removable/Mapoo/chroots/xenial... chroot: failed to run command 'su': No such file or directory WARNING: starting chroot system dbus daemon failed with code 127 chroot: failed to run command 'su': No such file or directory Unmounting /media/removable/Mapoo/chroots/xenial...

What do I do now to run it?

Thanks in advance.

@thunderbunker,

I've noticed that the bin folder is under chroots/xenial

That may be just xenial's /bin folder.
You may have to install / restore the host-bin files using crouton's '-p' option, something like -

sudo sh ~/Downloads/crouton -b -p /media/removable/Mapoo/

Then try one or more of the following -

sudo startunity -c /media/removable/Mapoo/chroots

cd /media/removable/Mapoo/ ; sudo ./bin/startunity -n xenial

Hope this helps,
-DennisL

[thunderbunker]

@DennisLfromGA

It correctly installed the bin folder! However, I still cannot run it. The first command says that startunity: command not found.

Also, the startunity file in the host-bin is still missing so I can't start it using

sudo sh '/media/removable/Mapoo/bin/startunity' like I always do.

How do I get the startunity file back?

Thanks.

[DennisLfromGA]

@thunderbunker,

It correctly installed the bin folder!

Then startunity should be in /media/removable/Mapoo/bin/
If it isn't then the restoral of the host-bin files didn't work correctly.

Try this, if it's in /usr/local/bin then it should find it -

sudo startunity -c /media/removable/Mapoo/chroots -n xenial

Also, if you have to use sudo sh ... then you might have to remount your external media as read-write using something like -

sudo mount -o remount,exec /media/removable/Mapoo

Hope this helps,
-DennisL

[thunderbunker]

@DennisLfromGA

I tried the command to install the host-bin files. The usual mount-chroot,edit-chroot, or the unmount-chroot were installed. However, the startunity files still is not installed.

`sudo sh ~/Downloads/crouton -b -p /media/removable/Mapoo/
Downloading latest crouton installer...

Startunity in not installed. Strange.

I tried looking for the folder /usr/local/bin but I couldn't find it. I ran sudo startunity -c /media/removable/Mapoo/chroots -n xenial and it gave me sudo: startunity: command not found

I also ran your last command, but no output was given.

What do I do now?

Cheers, Matt

@thunderbunker,

Something's fishy then,we need more info.
Please post the output of the following command:

sudo edit-chroot -c /media/removable/Mapoo/chroots -all

-DennisL

[thunderbunker]

@DennisLfromGA

I ran the command:

name: xenial
encrypted: no
Entering /media/removable/Mapoo/chroots/xenial...
chroot: failed to run command 'usr/local/bin/croutonversion': no such file or directory
Unmounting /media/removable/Mapoo/chroots/xenial...

What does this mean?

Cheers, Matthew

[DennisLfromGA]

@thunderbunker,

I'd say it means your chroot is not complete, I suspected that when all of your targets/desktops scripts didn't get restored. Perhaps the copy didn't complete successfully. It might be best to delete the chroot(s) under /media/removable/Mapoo/chroots/ and start over.

Hope this helps,
-DennisL

[thunderbunker]

@DennisLfromGA

What would be that command?

Cheers, Matthew

[DennisLfromGA]

@thunderbunker,

The command would be the aptly named delete-chroot
Please spend some time with the README, it will save a lot of headaches.

Hope this helps,
-DennisL

[thunderbunker]

@DennisLfromGA

I deleted the chroot successfully. Then, I copied it with the same errors as before. I used sudo enter-chroot -c /media/removable/Mapoo/chroots xenial.

This was the output:
Entering /media/removable/Mapoo/chroots/xenial... -su: 1: id: not found -su: 12: [: Illegal number: -su: 1: /etc/profile.d/crouton-pulseaudio-cras.sh: id: not found -su: 5: [: Illegal number: -su: 1: /etc/profile.d/crouton-unity-profiled.sh: /usr/local/bin/croutonversion: not found -su: 9: mesg: not found -su: 1: id: not found -su: 12: [: Illegal number: -su: 1: /etc/profile.d/crouton-pulseaudio-cras.sh: id: not found -su: 5: [: Illegal number: -su: 1: /etc/profile.d/crouton-unity-profiled.sh: /usr/local/bin/croutonversion: not found -su: 9: mesg: not found -su: 1: id: not found -su: 12: [: Illegal number: -su: 1: /etc/profile.d/crouton-pulseaudio-cras.sh: id: not found -su: 5: [: Illegal number: -su: 1: /etc/profile.d/crouton-unity-profiled.sh: /usr/local/bin/croutonversion: not found -su: 9: mesg: not found Unable to cd to '/home/matthew' Unmounting /media/removable/Mapoo/chroots/xenial...

(Also, how do you use markdown so that the code is neat and are in lines? Thanks.)

So then, I tried to install the bin files using:
sudo sh ~/Downloads/crouton -b -p /media/removable/Mapoo/
It said crouton wasn't found. That was because I was running a different account on the Chromebook. So I downloaded crouton on the other downloads folder. I installed the bin files and startunity downloaded, yippee!

Now, I try the sudo sh '/media/removable/Mapoo/bin/startunity' it should work. It doesn't.
It gives me Entering /media/removable/Mapoo/chroots/xenial... -su: 1: id: not found -su: 12: [: Illegal number: -su: 1: /etc/profile.d/crouton-pulseaudio-cras.sh: id: not found -su: 5: [: Illegal number: -su: 1: /etc/profile.d/crouton-unity-profiled.sh: /usr/local/bin/croutonversion: not found -su: 9: mesg: not found -su: 1: id: not found -su: 12: [: Illegal number: -su: 1: /etc/profile.d/crouton-pulseaudio-cras.sh: id: not found -su: 5: [: Illegal number: -su: 1: /etc/profile.d/crouton-unity-profiled.sh: /usr/local/bin/croutonversion: not found -su: 9: mesg: not found -su: 1: id: not found -su: 12: [: Illegal number: -su: 1: /etc/profile.d/crouton-pulseaudio-cras.sh: id: not found -su: 5: [: Illegal number: -su: 1: /etc/profile.d/crouton-unity-profiled.sh: /usr/local/bin/croutonversion: not found -su: 9: mesg: not found Unable to cd to '/home/matthew' Unmounting /media/removable/Mapoo/chroots/xenial... again.

What do I do now? I thought I had it.

Cheers, Matt.
