I tried to follow this… Pacman troubleshooting - Manjaro but I can’t figure out how to update my keys, if that’s even the problem.

The mirror in your mirrorlist returns html - when the update tries to download new databases - possibly a 404 error page.

Run pacman-mirrors to update your mirrorlist

sudo pacman-mirrors --continent

Then update databases with your system update

sudo pacman -Syyu

Didn’t work, and I tried different countries, no effect.

Then you may need to reset your mirror pool

sudo pacman-mirrors -c all

If you check the file using the file utility - you should get a response like

➜  ~ file /var/lib/pacman/sync/core.db
/var/lib/pacman/sync/core.db: gzip compressed data, from Unix, original size modulo 2^32 542720

If instead of the above response you got

/var/lib/pacman/sync/core.db: HTML document, ASCII text

Then the mirror responded with a custom html - most likely a 404 - Not Found response and you will have to look into why you get that response.

The response can be caused by a nginx server - serving a custom 404 document - in which case the response code will be 200 - OK and pacman expects a database but got html document which in turn generates the GPGME error.

No effect, same error.

return here (ask prev):

file /var/lib/pacman/sync/*

# file /var/lib/pacman/sync/core.db
/var/lib/pacman/sync/core.db: gzip compressed data, last modified: Wed Jul 28 08:54:18 2021, from Unix, original size modulo 2^32 1149952

Have you checked the other database using the same recipe.

Hello, I am having problems replying to the forum, not sure why. However, I found the solution. I will post it…

OK the *sig files in /var/lib/pacman/sync/ were damaged by my stupid Netgear WIFI extender! I could see the Netgear “mywifiext” URL in there.

I just deleted *sig and now Pacman works fine.

Seems to be SOLVED. Thanks.
