new to this linux stuff sorry
Not great for computers you don’t use often. If you do, make sure to
pacman -Sy archlinux-keyring
before you install new updates.
Pro tip there!
Thankfully, it appears this is no longer necessary in most cases since 2022: https://wiki.archlinux.org/title/Pacman/Package_signing#Upgrade_system_regularly
Though, it’s still worthwhile doing it for computers you don’t power on for most of the year, as the service likely hasn’t had a chance to run.
