Edit /etc/pacman.conf. Find the line [community] and comment it out, and the Include... mentioned below it, by inserting a # in front of them, like this:
#[community]
#Include = /etc/pacman.d/mirrorlist
Save, and retry.
Around two years ago, we’ve merged the
[community]repository into[extra]as part of the git migration. In order to not break user setups, we kept these repositories around in an unused and empty state. We’re going to clean up these old repositories on 2025-03-01 .
