Ubuntu16.04源码安装gitlab时出现Failed to connect to Gitaly... Error: 14:Connect Failed解决方法

git@gitlab:~/gitlab$ sudo -u git -H bundle exec rake gitlab:setup RAILS_ENV=production
Failed to connect to Gitaly...
Error: 14:Connect Failed

　　出现上述的问题时,需要修改文件/home/git/gitlab/lib/tasks/gitlab/setup.rake ,把第4行的check_gitaly_connection 注释掉,再次运行上述命令即可.
