And in #1297 someone is running into 08:47:48 <root> jabber - Login error: OAuth failure (Certificate verification problem 0x14: certificate hasn't got a known issuer)

I can repro this on is however working fine.

Both openssl s_client and gnutls-bin on the same machine see no problem and can find the right CA cert. I have no clue what GnuTLS (the lib actually used by BitlBee) is doing wrong here... I do see BitlBee opening the right ca-certificates.crt bulk file.

I reported the 0x14 error. I can confirm that works for me, but is still reporting the same error.

It seems to still be an issue.

I am still seeing this issue as well.

Resolution: fixed
Status: newclosed

I think this is/was an incompatibility between BitlBee/its use of GnuTLS, the GnuTLS version that comes with Ubuntu 14.04, and probably new TLS certs at Google.

Fortunately I've fixed this on by upgrading to the new LTS release, so this is all fine again there now.

If anyone else has this problem, again on 14.04 ... sorry, I did not actually find out what's wrong. GnuTLS debugging logs were utterly unhelpful as well, and the gnutls-cli cmdline utility did not reproduce this either as it was also compiled against a different libgnutls. :<
