Migrated from zorin to pop after a year for cosmic DE, so I’m still a beginner. I’ve seen there are many posts on similar errors but I didn’t wanna mess up my system with random codes, also, never encountered a problem with apt update.
Ubuntu Version: 24.04.
Desktop Environment: COSMIC (POP OS)
Problem Description: Sudo apt update is giving some errors
