I have recently upgraded my OS to Ubuntu 18.04 (fresh install via boot device). However, when trying the command:
sudo apt-get upgrade
It works fine until ~75% when it stops and says:
snapd.snap-repair.service is a disabled or a static unit, not starting it.
I'm not quite sure what this means and if I Crtl-Z to get out of it, any time I try to install anything I get:
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
and have to restart my computer to install anything.
