установка GitLab на CentOS7 не удалась из-за создания на ресурсе пользователя

Я пытаюсь установить gitlab на виртуальную машину под VirtualBox с CentOS 7

Я следую следующим инструкциям:
https://about.gitlab.com/downloads (для CentOS)

Я настроил gitlab.rb содержать:

external_url "http://gitlab.localhost.com/"

и когда я запускаю sudo gitlab-ctl reconfigure
Я получаю следующие ошибки:
