Reddit user Reyemxela: "Unknown trust when trying to install tmux
Even after updating pacman, making sure the archlinux-keyring package was up to date, etc., I was getting a an error when trying to install tmux, complaining that the signature was an unknown trust. This is mainly just due to the fact that the SteamOS arch mirror isn't super up-to-date, so the archlinux-keyring package is from 2022-09-27, and the author's key for the tmux package expired early 2023.
The various suggestions I've found (mostly for a regular arch install) include updating the archlinux-keyring, clearing keys and re-populating, etc., or even disabling key checking in your pacman.conf.
But the fix for this one was frustratingly simple: sudo pacman-key --refresh-keys "Full name of key author"
Running pacman-key --refresh-keys can take forever (like hours+ I guess), but come to find out you can just specify which key to update. Done."
These are somewhat dirty notes taken on a different PC.
signature is corrupted unknown trust when installing packages
Maybe need to install this: sudo pacman -Sy archlinux-keyring
or run this: sudo pacman-key --refresh-keys
Had to run sudo rm -r /etc/pacman.d/gnupg to fix wrong time errors on another try
