Signature from “User” is unknown trust

Posted on by — No Comments ↓

Today, I had another small adventure: updating my packages list on Arch Linux, I got this error:

error: confuse: signature from "Thorsten Töpper <[email protected]>" is unknown trust

:: File /var/cache/pacman/pkg/confuse-2.8-1-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).

Do you want to delete it? [Y/n]

How dealing with it?

There are two options:

  1. Following the Resetting all the keys section at the page of the packages management in Pacman, you remove all the keys installed in your system deleting the folder /etc/pacman.d/gnupg (obviously as root) and then after having run packman-key --init, adding the preferred keys;
  2. You can try to simply update the known keys, i.e. pacman-key --refresh-keys.

I did the second one and everything was fine.
