Curl (35) trying to install Gitlab Ubuntu server 18.04

Solution 1:

Usually when you have certificate errors like this you should always make sure you are accessing the correct websites and you are not redirected somewhere else.. but in your case I do not think it's the case.

In order to fix this do:

apt-get clean && apt-get update && apt-get upgrade

This should clean your repos cache and update everything. You have an old version of curl and OpenSSL and this issue I think is OpenSSL related.

Upgrade everything and it should work.

If not, to bypass ssl checks use:

curl --insecure https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.deb.sh
