I booted up my computer to find that I had an update available, and when I went to upgrade it, I was met with this.
I tried deleting /etc/pacman.d/gnupg, and running these commands: sudo pacman-key --init sudo pacman-key --populate sudo pacman-key --refresh-keys sudo pacman -Sc sudo pacman -Syu
but I still encountered the same error. (quick note: the refresh-keys command finished with this error:==> ERROR: A specified local key could not be updated from a keyserver. )
I repeated the above commands, except I added keyserver pool.sks-keyservers.net to /etc/pacman.d/gnupg/gpg.conf and ~/.gnupg/gpg.conf after running the init command. It still resulted in the same error, but I notied that the refresh-keys command was able to get a bunch of keys.
