Install GitLab on Ubuntu 20.04
Step 1. First, before you start installing any package on your Ubuntu server, we always recommend making sure that all system packages are updated.
sudo apt update sudo apt upgrade sudo apt install curl openssh-server ca-certificates
Step 2. Install Gitlab on Ubuntu system.
Now we add the GitLab repository:
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash
Once added, you can install the GitLab-CE package on Ubuntu system by using the following command:

nginx['redirect_http_to_https'] = true nginx['ssl_certificate'] = "/etc/letsencrypt/live/your-domain.com/fullchain.pem" nginx['ssl_certificate_key'] = "/etc/letsencrypt/live/your-domain.com/privkey.pem" nginx['ssl_dhparam'] = "/etc/gitlab/ssl/dhparams.pem"
We are then required to run a command to reconfigure GitLab settings:
sudo gitlab-ctl reconfigure
