[don't know]: invalid packet (ctb=2d)

I got this error on my CI

zero@Nu ~ % glep63-check --keyring /usr/share/pentoo/pentoo-keyring.asc                                                                                                                   1 ⨯

But it works properly when used in the same directory

zero@naga ~ % cd /usr/share/pentoo                                                                                                                                                        1 ⨯
zero@naga pentoo % glep63-check --keyring pentoo-keyring.asc
zero@naga pentoo %

Please update to work when given a path to the keyring

projg2 / glep63-check
