FYI -- found this after running into the same problem. This fixed it for me:
journalctl -u snap.docker.dockerd.service I saw many of these: docker.dockerd[1475]: failed to start daemon: pid file found, ensure docker is not running or delete /var/snap/docker/471/run/docker.pid Stopped the docker snap (snap stop docker) Deleted the stale pid, restarted docker (snap start docker) and all was well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834997 Title: Docker snap is stuck.
