You can force the lock off by removing the file, but it's not recommended without first closing the program that's holding the lock Safety.

Metod 1:


This will kill any processes opening the file before removing it.


sudo fuser -cuk /var/lib/dpkg/lock; sudo rm -f /var/lib/dpkg/lock



Same command for the apt cache lock:

sudo fuser -cuk /var/cache/apt/archives/lock; sudo rm -f /var/cache/apt/archives/lock

Try this command in terminal to find what is running:

ps -e | grep -e apt -e adept | grep -v grep

sudo kill -9 "process pid'

sudo rm /var/lib/dpkg/lock
sudo rm /var/cache/apt/archives/lock
