    • Can't start docker.

      I was looking at this thread. Someone needs to dumb it down for me. I"m a new linux and OMV user.
      Can't start DOCKER

      Scenario:
      Docker was working last night. I pulled an emby image and created a container yesterday before shutting down the box. Today docker won't start back up.

      Help please.
    • Purging the docker-engine package. Deleting the left over folders before reinstalling seem to do the trick. The daemon docker successfully restarts even after rebooting. Though I did also create a user to attach to the emby container. On the first round my OMV had no users.

      I still have an error when attempting to use the docker GUI plugin with the result of it being unusable. I negated the issue by using CLI.
