When I try to do : sudo apt-get install <package name> This is the response : E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
I tried to delete lock : sudo rm /var/lib/dpkg/lock Response: sudo: unknown user: root sudo: unable to initialize policy plugin
How should I go about this? Thanks!
