[arch-general] 'invalid radix64 character 2D skipped' with pacman-key --refresh-keys

Hello everybody, Does some of you encount problems with `pacman-key --refresh-keys` like me? I can't refresh my keyring due to some strange error messages: gpg: invalid radix64 character 2E skipped gpg: [don't know]: invalid packet (ctb=11) gpg: read_block: read error: Invalid packet gpg: mpi larger than indicated length (2064 bits) The full output is here: https://paste.archlinux.de/DY6FC/ Any idea how to solve this issue? I would guess it's something with gpg and it has nothing todo with the keyring or with pacman-key. Best regards Chris
