" error: failed to commit transaction (invalid or corrupted package (PGP signature)) "
Total newb here, arrived at Artix after looking for a lightweight Windows alternative with no systemd.
Getting above error when trying to update or upgrade ... anything. Not finding anything in the forums of this nature, so making a new post.
Started by trying to install a GUI for Pacman e.g. Pamac but yaourt deprecated and yay gets same error. I tried searching for a solution elsewhere, but the ArchLinux wiki just doesn't make sense to me *gasp* and other solutions lead me in an error loop with the same result, quoted above ^
If you want to see an example of my clumsy attempts, please see attached text file.
This is a fairly common error in pacman-based distributions and easily fixable too.

The --force pacman option has been deprecated recently, remove it or replace it with --overwrite (if needed).
I'll add to this and say the steps in that troubleshooting guide fixed this problem for me.
