Package: autopkgtest Version: 5.21 Severity: normal (I realise that posting this on debian-devel [1] was probably not the most appropriate place, as it's actually a bug report.)
I am not sure whether this is a bug in autopkgtest-build-lxc, a bug in lxc itself or a user error. Please feel free to redirect as appropriate! This is what I did: Step 1: I installed the lxc and autopkgtest packages That went smoothly. (lxc version 1:4.0.11-1, autopkgtest version 5.21; autopkgtest was already installed, and I installed lxc from Step 2: I ran the command "autopkgtest-build-lxc debian sid" as root. I got various warning messages to begin with: >>>>> lxc-create: autopkgtest-sid: storage/btrfs.c: btrfs_create: 938 Inappropriate ioctl for device - Failed to create btrfs subvolume "/var/lib/lxc/autopkgtest-sid/rootfs" lxc-create: autopkgtest-sid: storage/zfs.c: zfs_create: 735 Failed to create zfs dataset "zfs:lxc/autopkgtest-sid": lxc-create: autopkgtest-sid: utils.c: run_command_internal: 1588 lxc-create: autopkgtest-sid: storage/lvm.c: do_lvm_create: 165 Failed to create logical volume "autopkgtest-sid": Volume group "lxc" not found Cannot process volume group lxc lxc-create: autopkgtest-sid: storage/lvm.c: lvm_create: 623 Error creating new logical volume "lvm:/dev/lxc/autopkgtest-sid" of size "1073741824 bytes" <<<<< after which things ran smoothly for a bit: >>>>> debootstrap is /usr/sbin/debootstrap Checking cache download in /var/cache/lxc/debian/rootfs-sid-amd64 ...

Download complete. <<<<< but then there were lots of warning messages about libeatmydata.so interspersed with information messages; I assume that these are mostly harmless: >>>>> Copying rootfs to /var/lib/lxc/autopkgtest-sid/rootfs...ERROR: ld.so: object 'libeatmydata.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

I've restarted my system and started again. The above solution is very bad at least partly because /sys/fs/cgroup is type cgroup2. But I still can't start the LXC container, which makes running autopkgtest impossible. I did read the Debian Wiki pages on LXC and the /usr/share/doc/lxc/README.Debian.gz file, but to no avail. (I do have apparmor installed.) Any help much appreciated!
