Failed to synchronize all databases (invalid or corrupted database (PGP signature))

[FallingSky_42]

My problem is the same as this :

Error: failed to update multilib (invalid or corrupted database (PGP signature))

Update: I found that when i delete /var/lib/pacman/sync and just use sudo pacman -Syyu then everything is fine. As soon as I open the Updated Pacman GUI and start an update here it will fail. Could this come from some AUR Packages? Edit: When I run Pamac update I get the Error again: pamac update Preparing… Synchronizing package databases… Refreshing core.db… Refreshing extra.db… Refreshing community.db… Refreshing multilib.db… Error: multilib.db: GPGME error: No data Error: multilib…

I tried the solution, and I got this problem . The invalid or corrupted database (PGP signature) is still

Error: failed to update multilib (invalid or corrupted database (PGP signature))
