Server Certificate Verification Failed

[eligible]

Hi There
I'm using GITLab since the version 8.10.2, I've just upgraded to the latest version 9.1.3 and after that I'm not able to clone my projects, following error occur:

server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none

I've done the following steps but no luck ...
apt-get install --reinstall ca-certificates
update-ca-certificates

My OS is Ubuntu 14.04.5 LTS and the Web version with HTTPS is running fine, I've googled a lot but not find a correct way to resolve this issue.

Thanx in Advance

git config --global http.sslverify false


Worked for me, but is it safe?

Possibly related? I came here today to ask for help with a browser certificate problem. I have a PC and a laptop with (theoretically) identical Ubuntu 16.04 installations. Starting about a week ago, Firefox and Cisco applications on the PC claim that certain sites have invalid certificates (specific error: "Certificate is from an untrusted source"). Chromium is happy with the certificates. Firefox and Cisco on the laptop also report no problems. I am at a loss to explain why only certain application on one of two "identical" installations would report invalid certificates.

Anyone have any hints as to where to look for the problem?

Found the problem, although I don't understand the cause. Apparently Cisco also relies on Firefox for certificates. In Firefox, the certificate database was damaged (certutil could not open it). Deleting the profile and creating a new one solved the problem, both for Firefox and for Cisco AnyConnect. So this is unlikely to be relevant to the original poster's problem with GitLab.
