I can't seem to find the answer anywhere. So far I've figured out that I need to add (uncomment)
[multilib]
Include = /etc/pacman.d/mirrorlist
On "/etc/pacman.conf" and then run:
sudo pacman-key --init
When I run:
sudo pacman -S
I get:
warning: database file for 'multilib' does not exist
How can I fix this?
