Pacman errors: unknown key, name mismatch

[glitchdoctor]

When I try to run any pacman operation, I get:

$ sudo pacman -Syu

error: could not parse package description file 'haskell-gi-gdkx11-4.0.7-104/desc' from db 'extra'
 there is nothing to do

I have tried:

1. Instructions found here to rebuild the keys
2. Regenerating mirrors via pacman-mirrors --geoip and pacman -Syu --overwrite \* haskell-gi-gdkx11
3. Moving /var/lib/pacman/sync/extra.db and extra.files out of the way and re-downloading

All result in the same errors. What appears to be the offending package, haskell-gi-gdkx11 is not currently installed on my system that I can tell.

Can anyone suggest another course of action?

The db file contains invalid metadata and while read by pacman - the strucuture parser fails on the mentioned entry.

If your current country has a single mirror you will keep getting the same error as the db file is malformed.

Try using --fasttrack instead

sudo pacman-mirrors --fasttrack 10

Or you can set a specific mirror using the --api

sudo pacman-mirrors --api --url https://mirror.easyname.at/manjaro

Then clear the metadata folder

sudo rm /var/lib/pacman/sync/*

And rerun the sync

sudo pacman -Syu

Thanks much. These steps resolved the issue.
