bit off topic: bitbucket fingerprint problem

[Uwe Brauer]

A couple of weeks ago I had a problem with fingerprint on the bitbucket
site. Mads advised me

When this was done the following error poped up:

abort: error: _ssl.c:510: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

So that looks as if the fingerprint were missing.

Any ideas? Thanks
