Just tried to update my backup laptop that has been sitting idle for some months & recieved the following error message with instructions to request help on the forum - so here I am requesting help !:
E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?
