Server Certificate Verification Failed

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

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?

Yes safe. You can use it!
