Trying various ways to install Docker on Buster I have now run into this.
I get the message that E: dpkg was interrupted and to run the sudo dpkg --configure -a command.
When I do I get this:
Created symlink /etc/systemd/system/multi-user.target.wants/containerd.service -> /lib/systemd/system/containerd.service.
and after a couple of minutes my ssh session disconnects to that Raspberry Pi 4. I can ssh back into it immediately but does anyone know what to do to get past it?
