How To Fix “invalid or corrupted package (PGP signature)” Error In Arch Linux

Today, I tried to upgrade my Arch Linux server using command 'sudo pacman -Syu', and I got the following error:

[...]
:: File /var/cache/pacman/pkg/libpsl-0.16.1-1-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n] y
error: failed to commit transaction (invalid or corrupted package)
Errors occurred, no packages were upgraded.

Then, I ran 'sudo pacman -Syyu' command, but still no luck. I kept getting the same error no matter how many times I tried. After a bit of search on Google and Arch Linux forums, I found that there are new keys in the archlinux-keyring package.

To fix this issue, we need to update the archlinux-keyring package.

To do so, run:

$ sudo pacman -S archlinux-keyring

Sample output would be:

The above command will update the new keys and disable the revoked keys in your Arch Linux system.

Again, I tried to upgrade my Arch Linux using command:

$ sudo pacman -Syu

This time the upgrade process went well without any issues.

Thanks for stopping by!

sudo pacman -Sy gnupg archlinux-keyring manjaro-keyring fast, important
sudo pacman -Syu big download/install
[clear is deleting operation !]
pacman-key –refresh-keys fast, important, impact

This only worked for me after removing and regenerating pacman keys using the first part of this tutorial : https://forum.manjaro.org/t/how-to-solve-keyring-issues-in-manjaro/4020
