As seen in my control bits above, you've got the wrong Docker, unfortunately. I've reassigned the bug appropriately from the wmdocker utility to the Docker Engine. > Setup: debian buster upgraded to bullseye using apt dist-upgrade > In buster i had few docker containers running without issues.

Frankly though, I'd suggest (hah) that it should be downgraded to Suggests instead -- on a modern init system (systemd, openrc, etc), the init system sets up and manages the cgroup hierarchy, which ends up being a lot more stable/reliable than the "cgroupfs-mount" package ever was, especially now that we have cgroupsv2 (which that package doesn't support, and Docker's cgroupsv2 support relies on systemd anyhow). I suppose we could use something "clever" like "cgroupfs-mount | systemd-sysv" but that still seems pretty fragile IMO. ♥, - Tianon 4096R / B42F 6819 007F 00F8 8E36 4FD4 036A 9C25 BF35 7DD4
