Signature errors when updating - Brave, Mesa

Hello,

I’m getting the following errors when using pamac

sudo pamac upgrade                                                                             ✔

Error: Failed to commit transaction: invalid or corrupted package (PGP signature):

Found a forum thread which recommended fixing it like this:

sudo pacman-mirrors -f5 && sudo pacman -Syyuu

But that errors out too:

Do you want to delete it? [Y/n] 

Also tried

sudo pacman-key --refresh-keys

But that changed nothing.

I never changed anything about pacman / pamac configuration other than set mirrors.

I’m also still a newbee, but to me it looks the keyrings are not updated.

This worked, thank you!
