I tried to upgrade Ubuntu from 18.04 to 18.10, but there was an error with Docker. I tried to install it via the terminal, but it got stuck while "preparing to unpack".
I force-restarted the system and now I see a notification on the Software Update app offering me to download and install the latest update for Docker.ce, but the same thing happens - it gets stuck while "preparing to unpack".
Now every time I reboot/shutdown -- it just won't shut down due to
A stop job is running for Docker Application Container Engine (13min 58s / no limit)
I only wanted to upgrade the system, but it seems that I've done something wrong in the terminal.
