There are 2 possibilities;

  1. You may be currently running another process with apt, if this is the case, you can wait for it to complete, another option is to simply kill the process.

  2. A previous process (e.g. when apt was executed in the past) did not delete the lock file, this file would exist in /var/lib/dpkg/lock-frontend, then if there wasn't a process using it at all, you would have to remove it manually with sudo rm /var/lib/dpkg/lock-frontend, then force package reconfiguration with sudo dpkg --configure -a
