How to setup GitLab - Debian 8 <p>I am executing the below command, however i get an error. Someone please assist.</p> <pre><code># curl https://packages.gitlab.com/gitlab/gitlab-ce/packages/debian/jessie/gitlab-ce_8.1.2-ce.0_amd64.deb/download curl: (60) SSL certificate problem: certificate is not yet valid </code></pre> <p>If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL).</p>
