[Tails-dev] certificate error for immerda.ch

This may already be known by those that can fix it, but I'm getting an
error when accessing git-tails.immerda.ch.


With Git:
fatal: unable to access 'https://git-tails.immerda.ch/tails/': server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none


In Firefox:

git-tails.immerda.ch uses an invalid security certificate. The
certificate is not trusted because the issuer certificate is unknown.
The certificate is only valid for git.tails.boum.org (Error code:
sec_error_unknown_issuer)
