I found this similar issue: moby/moby#29496 (comment)

The comment I linked recommends doing some extra setup work in order to get cgroups working. Can you try that and see if it works?

@Moshyfawn If you're running Fedora 31, this is likely the solution until this issue is closed.

1. Edit /etc/default/grub
2. Add the following line below GRUB_CMDLINE_LINUX:

systemd.unified_cgroup_hierarchy=0

3. Run grub2-mkconfig
4. Restart the system

For more info, see CGroupsV2 on Fedora wiki.

@Moshyfawn Let us know if that solution works! Thanks for finding it @MarttiR!

@MarttiR thanks a lot, it worked!

• Linux 5.3.11-300.fc31.x86_64
• Docker version 19.03.5, build 633a0ea838

The solution of @MarttiR did not work for me, and I think the Fedora 31 documentation had an update for this issue :
https://fedoraproject.org/wiki/Common_F31_bugs#Docker_package_no_longer_available_and_will_not_run_by_default_.28due_to_switch_to_cgroups_v2.29

Thus, another way to disable CGroupsV2 and allow Docker to run seems to be:

• sudo grubby --update-kernel=ALL --args="systemd.unified_cgroup_hierarchy=0"
• reboot

(or use podman that suport CGroupsV2 instead of Docker)

[Moshyfawn]

Sorry for the late reply, being very busy.
I've tried @MarttiR's solution but it didn't work for me. Even had to deal with the secure boot and resetting my grub config. The solution @H--o-l mentioned did it.
Those seem like a similar two similar solutions, tho. Maybe I've made some mistake.

Working solution:
sudo grubby --update-kernel=ALL --args="systemd.unified_cgroup_hierarchy=0"

P.S. @H--o-l mentioned using podman but it still can't fully replace docker at least regarding docker-compose. That's why I ran into this issue in the first place

I had the same problem with docker on fresh installation of Fedora 31 and Fedora 31 Server.
@H--o-l solution (using sudo grubby --update-kernel=ALL --args="systemd.unified_cgroup_hierarchy=0" then rebooting) is working like a charm in both cases.

Can't use podman as I'm using docker-compose (same as @Moshyfawn).

[mmarquezv]

I had the same problem and sudo grubby --update-kernel=ALL --args="systemd.unified_cgroup_hierarchy=0" worked fine. Thanks!

[bwateratmsft]

I'll close this issue as external, seems to be a Fedora thing.
