Fedora 31: Docker Fix

I’ve updated my laptop to Fedora 31 over the Christmas holidays. Pretty much everything works as it did before. Except for Docker, which suddenly fails to start the service.

A quick Google search pointed to the discussion in this bug report, where I found the solution that worked for me:

  1. Edit /etc/sysconfig/grub
  2. Append systemd.unified_cgroup_hierarchy=0 to the GRUB_CMDLINE_LINUX variable
  3. Run “grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
  4. Reboot

Once the machine came back up gambling bitcoin, docker service was running normally.
