Hello,

I have some trouble to update my system.
It ends up with a web search and a solution which works for everyone but for me:

Welcome to the forum!

Can you do a normal update

sudo pacman -Syu

?

EDIT:

I found this:

https://forum.endeavouros.com/t/trouble-updating-invalid-pgp/17055/3

Which solved the problem. Could anybody explain why this happens?
