Package: autopkgtest Version: 5.17 Severity: normal Tags: patch lxd is not packaged for Debian at the moment (ITP #768073), so the common way to install it on Debian is through snapd.
Unfortunately executing any confined snapped binaries outputs a line on stderr: > WARNING: cgroup v2 is not fully supported yet, proceeding with partial > confinement autopkgtest's VirtSubProc will (by default) fail if anything is emitted to stderr, breaking the build immediately: > <VirtSubproc>: failure: ['lxc', 'launch', '--ephemeral', > 'autopkgtest/debian/unstable/amd64', 'autopkgtest-lxd-uqbaqs'] unexpectedly > produced stderr output `WARNING: cgroup v2 is not fully supported yet, > proceeding with partial confinement > ' > Undefined return value after 'open' > E: Error creating chroot session: skipping python3.10 This message can't be suppressed, as far as I am aware, so the easiest is to just not fail when we see them. I've been using sbuild + autopkgtest + snapped lxd successfully with this patch for several months. There are probably prettier ways of dealing with the problem (and even filtering these messages from the output), but this has the benefit of being simple.
