Whenever I tried to update my system Using

sudo apt update && apt upgrade

I found this error

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'm using Ubuntu 20.04.1 LTS x86_64 with plasma

    Here, sudo was attached to apt update not apt upgrade. Try running sudo apt update && sudo apt upgrade. – Kulfy Dec 30 '20 at 08:38
  • You will have to use sudo apt update && sudo apt updrade The way you run it only apt update is run with sudo. The shell the commands on either side of "&&" as different commands. – Soren A Dec 30 '20 at 08:41
  • @Kulfy, I think you should post your first comment as an answer to the question. – Katu Dec 30 '20 at 10:34
