Unable to update system... Signature is invalid

[Esgath]

So I’m pretty much unable to update my system. I tried updating mirrors and i tried everything in this post:

[FAQ] Issues with “signature is marginal trust”, "signature is unknown trust", or “invalid or corrupted package”

If you’re getting an error similar to “Can’t update: signature from *** is marginal trust” or “invalid or corrupted package” you probably just need to update your package signing keys: sudo pacman -Sy archlinux-keyring endeavouros-keyring sudo pacman -Syu Also make sure your system clock is correct! Of course, it’s also possible that the package file actually is corrupt. Remove it from /var/cache/pacman/pkg/ so pacman will download it again. If no package file is explicitly mentioned then yo…

EXCEPT :
" And if this still doesn’t work, and you trust that the packages are actually correct and not corrupt and haven’t been interfered with, then you can force (re)installation of the keyring packages:

sudo pacman -U /var/cache/pacman/pkg/{archlinux,endeavouros}-keyring*.pkg.tar.zst

then try again."
I still keep getting “signature from “David Runge dvzrv@archlinux.org” is invalid”
“Do you want to delete it? [Y/n]”
i chose N and it keeps giving me other similar messages about signature.

You could try resetting your keys:

@Esgath ,

sudo pacman-key --refresh-keys

Search here offers this.

I already did this in the linked post using those steps:
"
sudo mv /etc/pacman.d/gnupg /root/pacman-key.bak
sudo pacman-key --init
sudo pacman-key --populate archlinux endeavouros
sudo pacman -Syy archlinux-keyring endeavouros-keyring
sudo pacman -Syyu
"

Okay, so i did the following:

1. Removed downloads of packages that show as invalid signature:

sudo rm /var/cache/pacman/pkg/jbigkit-2.1-7-x86_64.pkg.tar.zst
sudo rm /var/cache/pacman/pkg/foomatic-db-nonfree-ppds-3:20230903-1-any.pkg.tar.zst
sudo rm /var/cache/pacman/pkg/unrar-1:6.2.11-1-x86_64.pkg.tar.zst

It showed me that i have problems with “archlinux.thaller.ws”, i kept updating my mirrors earlier but it kept adding it, so i picked mirrors from different region.
2. run
sudo pacman -Syu

Problem solved, it seems the mirror stuff was the issue.
