You can refer to the link Unable to lock the administration directory (/var/lib/dpkg/) is another process using it? — minhky, Jun 18 '17 at 09:37
you have to close muon (the graphical updater) before doing the command line — ravery, Jun 18 '17 at 09:48

Only one program can get lock on the admin directory at a time. Since you have the graphical software installer open, it has the lock, and your terminal command can't work.

Close the graphical installer and try your command again. As a last ditch effort, reboot and try again.
