Accidently installed docker snap while having docker dpkg installed.

Hi, I am having a rather annoying issue, while I was messing around in a VM I apparently disconnected through SSH. I happily did sudo snap install docker on my host machine that was running a few development containers. After noticing my mistake I uninstalled the snap package, but it was already too late.

I attempted to remove and reinstall my normal docker install but that didn't helped. Basicly docker can not remove/stop/kill/start containers because permissions issues.

Starting

ERROR: for db  Cannot start service db: mkdir /var/run/docker/libcontainerd/containerd/15cb2e0b612ac94ea3a48a16f94c045dbeb02a90867d106169022459b8576674: file exists

Stopping a new container

Cannot stop container e51a26232f662a497c2523224f811d78ab9b5786d1acff27271a32ea4f6cff59: Cannot kill container e51a26232f662a497c2523224f811d78ab9b5786d1acff27271a32ea4f6cff59: rpc error: code = 7 desc = permission denied

It wouldn't be that bad if I could get 1 container running to get the prepared data of a postgresql container.

As for the issue. It would be nice if the snap package fails to install if an older docker installation has been installed.

Thank you

I solved my issue, the snap docker actually was already running some of my containers, but upon removing the snap package it didn't correctly shut those down. Creating zombie processes of docker-containerd-shim. I don't know if it is worth looking into this tho. Restarting the server cleaned those up and I was abbe to restart my containers.

Thanks for the feedback. The snap and non-snap versions don't get along well, so we don't support upgrading from one to the other (discussed previously -
#4). In general since they store data in different places, most of the problems are related to apparmor profiles, which a reboot can help with. I don't think it makes sense to try to have the snap detect this scenario. I'll keep an eye out for the zombie issue. Closing, but feel free to continue the conversation. 👍
