I can’t install things using Terminal, this comes up. I used ‘sudo apt-get install vlc’
sudo apt-get command not found
Not going to lie, I giggled.
Arch linux uses Pacman as a package manager. Instead of doing
sudo apt-get install vlc, you will do
sudo pacman -S vlc. That -S command is for installation.
I would look into the link anarch posted to see the differences. (https://wiki.archlinux.org/index.php/Pacman_Rosetta)
Another read would be the pacman wiki, as it explains everything in depth: https://wiki.archlinux.org/index.php/Pacman
