GPGME error on Arch Linux 32bit

Question

I need to fix this issue with GPGME error. I cannot upgrade or install anything. This is what I get in terminal:

sudo pacman -Syyu
error: GPGME error: No data
error: GPGME error: No data
error: GPGME error: No data

I tried lots of workarounds like pacman-key --init and pacman-key --populate archlinux nothing helps.

If I edit etc/pacman.conf and insert SigLevel = Never to core and community then I get this output:

sudo pacman -Syyu

SOLVED!

Finally I managed to solved this. I'll write what I've done.

sudo rm /var/lib/pacman/sync/*db.sig*

Edit & uncomment:

sudo nano /etc/pacman.d/mirrorlist

## Germany
Server = http://archlinux32.vollzornbrot.de/$arch/$repo
Server = https://archlinux32.vollzornbrot.de/$arch/$repo
Server = http://mirror.archlinux32.org/$arch/$repo
Server = https://mirror.archlinux32.org/$arch/$repo
# note: you need to resolve via openNIC (or similar) to access the next mirror
#Server = http://mirror.archlinux32.oss/$arch/$repo

Then:

sudo pacman-key --init

sudo pacman-key --populate archlinux

sudo pacman -Syy

sudo pacman -Syyu

Done!
