I’ve created a key pair using ssh-keygen then I’ve uploaded it to the SSH Keys section of gitlab.

After a few minutes I’m able to download the repository, modify it, push changes as it should work.

However, I come back the next day and the single sign-on access using ssh no longer works. At one point yesterday I deleted the key from the SSH keys section of gitlab and repasted the exact same key. A few minutes later it worked again. However, again I came in the next day and it doesn’t work again. Here is what I see when I try to get verbose output from ssh:

Any ideas on how to fix this?

Hope this helps, let me know!

The solution on this site is to execute:
sudo -u git -H bundle exec rake gitlab:shell:setup RAILS_ENV=production

First it gave me an error saying that git is an unknown user so I replaced the call with the user name I’m building the code under.

Then It gave me an error saying bundle is not a known program.
So I installed ruby-bundler package.

Then Executed the command again and now get an error:
Could not locate Gemfile or .bundle/ directory

I’m not sure what this Gemfile or the .bundle directory is used for or how to set this up.
