docker already installed

sudo clickable setup-docker
Asking for root to start docker

groupadd: Gruppe »docker« existiert bereits.
Command '['sudo', 'groupadd', 'docker']' returned non-zero exit status 9

Already having docker shoudn't break the command

Agreed, I'll get that fixed.

@bhdouglass any workaround to get this going. I tried doing a sudo groupdel docker but that didn't help as I was then bitten by

usermod: user '$USER' does not exist
Command '['sudo', 'usermod', '-aG', 'docker', '$USER']' returned non-zero exit status 6

I just pushed a fix for both of these issues. v2.1.2 will be available in the ppa soon.
