What is this, and why does it cause my -Syu update to fail?

Have tried twice this week to do a sudo pacman -Syu system update, and have encountered the same error each time:

error: eos-translations: signature from “manuel <manuel@endeavouros.com>” is unknown trust

It looks like this is a translation package with an untrusted source? Is there a way to remove/bypass this in a way that will allow me to upgrade my packages?

Try updating the keyrings (this appears to be only related to the EOS keyrings, but it won’t hurt to update both the arch and EOS keyrings:

sudo pacman -Sy archlinux-keyring endeavouros-keyring && sudo pacman -Su

4

Also update/change your mirrors. Could be a specific server outdate
