@Keneda Thank you for your help. I did not find anything else inside the phablet file then the home files I can find without loging in with my password. I have asked for an account on Volla user forum. I guess the problems I am facing may problems with Volla hardware or software?

I have Ubuntu Touch 20.04 And yes it should work on Quintus.

@Keneda Sorry, I do not know how to do that.

How do I solve this problem as a new linux user?

The installation stops with this message:

W:Failure trying to run: chroot"/home/phablet/.cache/libertine-container/focal/rootfs" dpkg --force-depends-- install /var/cache/apt/archives/ libc6_2.31-0ubuntu9_arm64.deb
W:See /home/phablet/.cache/libertine-container/focal/rootfs/debootstarp/debootstarp.log for details (possibly the package /var/cache/archives/ libc6_2.31-0ubuntu9_arm64.deb is at fault)
