I was Using ubuntu 20.04 and I wanted to upgrade it to 20.10. While upgrading I closed the terminal beacause it stoped to work and I can't open apps like Settings ubuntu software and the terminal, I even can't restart.I tried to use the terminal in Vs Code but I get always this error message E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 73120 (groovy) N: Be aware that removing the lock file is not a solution and may break your system. E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?
