Gitlab Installation stuck at start gitlab-runsvdir

OS: Ubuntu
Steps I’m following: https://about.gitlab.com/install/#ubuntu

What should I do to setup Gitlab properly?

Gitlab EE installation is stuck at the following point:
* execute[systemctl start gitlab-runsvdir] action run

Following is the output of ps -ef | grep gitlab:
