[packman] Certificate on PMBS

[Jörg Lorenzen]

Hi Packman admins,

I think there is a problem with the digital certificate on 
https://pmbs.links2linux.de/,
since some days I get the following error message with Firefox: 
(Errorcode: sec_error_untrusted_issuer).
With Chromium I get the following message: The website's security 
certificate is not trusted.
Ignoring this message only works with Chromium, there is no way to 
continue with Firefox.

Greetings,
Jörg
