Hi, I have problems to update. I am getting:

sudo pacman -Syyu:

error: GPGME error: No data
error: GPGME error: No data
error: GPGME error: No data
:: Synchronizing package databases...
 core                  143,2 KiB   197 KiB/s 00:01 [######################] 100%
 extra                   8,3 MiB  3,72 MiB/s 00:02 [######################] 100%
 multilib              147,9 KiB  1138 KiB/s 00:00 [######################] 100%
error: GPGME error: No data
error: GPGME error: No data
error: GPGME error: No data
error: failed to synchronize all databases (invalid or corrupted database (PGP signature))

I already tried the common approach, but still have the same result.

sudo cp -f "/etc/pacman.conf" "/etc/pacman.conf.orig"
sudo sed -i 's/SigLevel.*/SigLevel = Never/' /etc/pacman.conf
sudo pacman -Syy gnupg archlinux-keyring manjaro-keyring --ignore manjaro-system
sudo mv -f "/etc/pacman.conf.orig" "/etc/pacman.conf"
sudo pacman -Syu

What else do I need to update or fix?

Thanks!
