Description Andreas Schwab 2020-06-03 13:40:22 UTC

With the recent expiration of the AddTrust root certificate gnutls fails to verify a lot of TLS connections because that certificate is being sent as part of the certificte chain.  See <https://gitlab.com/gnutls/gnutls/-/issues/1008> for details.

I temporarily disabled the test in order to get the recent security fixes to Factory (bug 1172506, bug 1172663), so this bug will get fixed by request https://build.opensuse.org/request/show/812790.
