w: failure to run:chroot

Hi, i'm running ubuntu touch on Redmi Note 9 pro (global) and i have probem with making conteiner. This is the error message i got.

As you've probably seen here, I have exactly the same problem on shiftMQ6 running xenial (currently devel 930).

@suchy I have the same issue on my Redmi Note 9 Pro as well. Before on OTA-23 Libertine was working without problems, then I reinstalled UT and updated to OTA-24 and I wasn't able to create container since. Maybe it has something to do with latest update or I don't know what could be causing this problem.

I have the issue ever since installing.
For that particular issue, I switched to devel and jumped over 50 updates but this issue persists. Anybody any idea how to solve? Tried different things myself without much success as libc6_2.23 is quite outdated it seems?

Same cannot get chroot what about instead of using chroot just give libertine special rw access and just use the system more normal ....idk iv never gotten libertine to work

Hey Fellows,

I think I've found the cause of this issue.
And some sort of Work Around.
When running the Libertine thing via terminal, you can cancel the process once you hit
the extracting coreutils stage. This will keep all the container files incl. the debootstrap.log file.

In there it says:

Preparing to unpack .../libc6_2.23-0ubuntu11.3_arm64.deb ...
ERROR: Your kernel version indicates a revision number
of 255 or greater.  Glibc has a number of built in
assumptions that this revision number is less than 255.
If you\'ve built your own kernel, please make sure that any
custom version numbers are appended to the upstream
kernel number with a dash or some other delimiter.

uname -a shows:

Linux ubuntu-phablet 4.14.288-halium+ #1 SMP PREEMPT Sat Aug 27 21:08:42

That means, the 288 causes the error. Which is related to this bug.

I am using a Terminal SSH connection. And I can reproduce the issue with:

sudo apt-get update && sudo apt-get install --reinstall libc6

I've adapted the common used work around for this, to replace the kernel revision number by
replacing the /bin/uname with an executable script placed in ~/Downloads/uname.

#!/bin/bash

unameparams="$(uname.orig "$@")"

revision_number=$(echo $unameparams | grep -oE '[0-9]{1}\.[0-9]{1,2}\.[0-9]{1,3}' | grep -oE '[0-9]{3}')

if [[ "$revision_number" > "254" ]] ;then
  echo $unameparams | sed -E 's/[0-9]{1}\.[0-9]{1,2}\.[0-9]{1,3}/4.14.250/'
  exit
else
  uname.orig "$@"
fi

sudo mv /bin/uname /bin/uname.orig
sudo chmod 755 ~/Downloads/uname
sudo cp ~/Downloads/uname /bin/uname

This fixed the issue with the static call

sudo apt-get update && sudo apt-get install --reinstall libc6

But this doesn't worked for the libertine container, because it installs its own coreutils within chroot.

I am using this command to create the container.
libertine-container-manager create -i linuxapps -n linuxapps

To fix it for the creating process as well, I had to hit the target right after the Extracting Coreutils stage during
the process. Which was impossible to do manually, so I used a in second SSH Terminal session a while loop
to wait for uname to exist within the chroot and then replace it.

while ! test -f "/home/phablet/.cache/libertine-container/linuxapps/rootfs/bin/uname"; do
  sleep 0.1
  echo "Still waiting"
done

mv ~/.cache/libertine-container/linuxapps/rootfs/bin/uname ~/.cache/libertine-container/linuxapps/rootfs/bin/uname.orig
cp ~/Downloads/uname ~/.cache/libertine-container/linuxapps/rootfs/bin/uname

I've executed the while loop once the process reached the Extraction State, yes a lot of echo "Still waiting" were shown,
but it hit the target perfectly and the process continued.

Unfortunately, during the whole process, the ~/.cache/libertine-container/linuxapps/rootfs/bin/uname gets replaced with the real uname file quite often, but with much less time sensitivity. So I had plenty of time, each time, to check with:

ls -l ~/.cache/libertine-container/linuxapps/rootfs/bin/uname*

the size of it, and then manually cp the script with

cp ~/Downloads/uname ~/.cache/libertine-container/linuxapps/rootfs/bin/uname`

The whole process finshed after a while, with another warning, but the container was created.

I guess, to fix this thing in general, UBPorts needs to switch to
a libc6 version, that has abandoned this revision number check. i.e. glibc - 2.27-3ubuntu1.6 as stated in the last post of the above named bug.

Nice work @NewBit

I have a Redmi note 9 pro and I also have the same issue, I hope that in the next OTA they can fix it.

This fix worked for me, with Redmi Note 9 Pro. Thanks!
