Error updating system (Unknown trust)

General system EndeavourOS repo
1

Today I was updating my system via pacman and an error was shown;

error: yay: signature from "manuel <manuel@endeavouros.com>" is unknown trust

I saw a similar error where “EndeavourOS” was the unkown trust and they said to use:

sudo pacman-key --lsign-key “EndeavourOS”

But I don´t know if I should because is not EndeavourOS is Manuel

I’ve tried to update EOS for several days. The following error message pops up.

error: yay: signature from “manuel manuel@endeavouros.com” is unknown trust
:: File /var/cache/pacman/pkg/yay-12.0.5-1-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).

When I gave the ‘sudo pacman -Sy endeavouros-keyring’
command, the following error message appeared.

error: failed to synchronize all databases (failed to lock a database).

How should correct this error in order to run the following commands?

sudo pacman -Sy endeavouros-keyring
sudo pacman -Syu
