Docker is not a package in Fedora.

1. Since Fedora 31, Fedora uses cgroup v2, and Docker is not yet compatible (it will be in next Docker release). To use Docker on Fedora >= 31, you need to revert to cgroups v1:

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

Cf. https://fedoramagazine.org/docker-and-fedora-32/

2. Which package do you use? Please copy the output of:
- rpm -qf /usr/bin/docker
- docker system info

On Fedora 32, using Fedora package (i.e. moby-engine) and not the Docker CE distribution, you should have more precise error message...

Bad For install podman-docker Not search  cockpit-docker on Fedora 32

Using Docker At Docker-ce Repo

repo https://download.docker.com/linux/fedora



dnf remove podman-docker cockpit-docker  fist

then install docker-ce

I maintain Fedora package moby-engine, not upstream package docker-ce.

However, see upstream documentation: https://docs.docker.com/engine/install/fedora/


3. Cgroups Exception: For Fedora 31 and higher, you need to enable the backward compatibility for Cgroups.

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

After running the command, you must reboot for the changes to take effect.


Please follow these instructions to revert to Cgroups v1.
