What to do next ?

EndeavourOS keyring updated, users should update soon

Today package endeavouros-keyring was updated. This means users should update this package as soon as possible in order to avoid issues when updating other packages. Similar to what we have been doing when Arch keyring updates, you should run commands sudo pacman -Sy endeavouros-keyring sudo pacman -Syu Edit 2023.05.28: Alternatively, you can run command eos-update

I would do: sudo pacman -Sy endeavouros-keyring && sudo pacman -Su first.

If that won’t resolve the issue, then follow the instructions in the link posted.
