Hi,
I tried to install docker following the instructions on: https://docs.docker.com/engine/install/fedora/#install-using-the-repository
I get these errors and cannot see what's wrong:
root@slimbook:~# systemctl enable --now docker Created symlink '/etc/systemd/system/multi-user.target.wants/docker.service' → '/usr/lib/systemd/system/docker.service'. Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xeu docker.service" for details.
