Error possibilities when upgrading Linux:

• Docker may not start after the upgrade.
  • This happens if the docker has also been updated and it connects to our management server.
  • Fix:
    • Open the /lib/systemd/system/docker.service file and remove the following part from the line starting with ExecStart:
      • -H unix:// OR -H fd://
      • Example:
        • From: ExecStart=/usr/bin/dockerd -H fd:// –containerd=/run/containerd/containerd.sock
        • To: ExecStart=/usr/bin/dockerd –containerd=/run/containerd/containerd.sock
