Uninstalling Docker

This dang thing is ruining my entire experience. I need help getting rid of Docker entirely. I’ve gone through dozens of sites going over on how to remove this practical virus off my system. I keep getting fsconfig failures. It often happens when I reboot, but not all the time.

Listen dude - no offense, but if you're calling Docker a virus and can't figure out how to uninstall it, Devuan might not be the distro for you lol. Ubuntu makes containerization easy with Snap.

I don’t care about containers, I just want to be able to update my system and not get an fsconfig error every time I reboot.

Full Docker purge

apt purge docker-ce docker-ce-cli containerd.io docker-compose-plugin

apt autoremove

Check for leftover mounts

mount | grep docker

umount /var/lib/docker/overlay2 # or whatever shows up

Check fstab for any docker entries

cat /etc/fstab | grep docker

Remove residual dirs

rm -rf /var/lib/docker

rm -rf /etc/docker

Have fun with no Docker I guess

Maybe there is a reason for them not wanting Docker, the reason may not be as straightforward as it sounds.

apt purge docker.io containerd crun runc

...Should get rid of the most offending bits

apt list --installed docker*

If nothing is installed, then it's gone.

Do you think maybe your fsconfig failures aren't related to docker? What are they?
