There's no "docker" on fedora 33. This is probably a moby-engine bug.

Comment 2 bugzilla 2020-10-06 08:11:58 UTC

thanks, you are right: moby-engine-19.03.13-1.ce.git4484c46.fc33.x86_64

Comment 3 Olivier Lemasle 2020-10-06 09:06:39 UTC

Hi,

Sadly, moby-engine is not yet compatible with cgroups v2, which is used by default by Fedora since Fedora 31 (actually, the error message is printed by runc, which does not work yet with cgroups v2).

To revert to cgroups v1 and use moby-engine, you can:

- Run: sudo grubby --update-kernel=ALL --args="systemd.unified_cgroup_hierarchy=0"
- Then reboot

Otherwise, you can explore using podman, but it does not replace docker/moby-engine in every scenario.
