UPDATE: The problem has been fixed on identi.ca’s side. Maybe the workaround will be useful to others in some other context at some other time. I will also remove the certificate mentioned below from my system. It won’t be needed any longer, and who knows what nasty side effects it might have going forward…
I ran into this problem today where Gwibber (the micro-blogging client) on Ubuntu would not work with identi.ca anymore. The bug report referred to the log file ~/.xsession-errors, which contained this message:
Traceback (most recent call last):
File “/usr/lib/python2.6/dist-packages/gwibber/microblog/network.py”, line 53, in __init__
self.curl.perform()
error: (60, ‘server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none’)
