Attempting update today, I received: error: mksh: signature from "Thorsten Töpper <........@freethoughts.de>" is unknown trust :: File /var/cache/pacman/pkg/mksh-52.1-1-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)). Do you want to delete it? [Y/n] n error: failed to commit transaction (invalid or corrupted package) Errors occurred, no packages were upgraded. Is this a know issue? How to work around (correctly)? -- David C. Rankin, J.D.,P.E.
