I am trying to run this command:
sudo apt-get update && apt-get upgrade but I keep getting these errors
E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?
I read in another answer that by using
sudo these errors will be solved. But in my case I'm already using sudo. How to solve these errors?
