Unable to debootstrap for Ubuntu Jammy with debos docker image

[RadxaYuntian]

Jammy uses zstd to compress their packages, which is not supported by Debian Bullseye's dpkg, which is also used by the docker image. I tried to install some custom deb packages from debug shell, but it appears I cannot write to /usr inside docker so dpkg -i failed.

dpkg zstd support is not in debian unstable yet: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892664

Perhaps a workaround could be to create an Ubuntu-based Docker image ?

That's the first idea I have. Although I'm not sure if the situation has been changed regarding debos's Ubuntu host support.

Did some testing myself with Ubuntu docker. Ubuntu doesn't have UML package, so that has to be removed from the Dockerfile. However fakemachine doesn't seem to work in docker so I have to pass --disable-fakemachine and run container in privileged mode since debbootstrap expect to run as root. Currently I'm stopped at the following error:
