GitLab: Not allowing me to push

Question

My friend has recently set up a GitLab on his Centos machine, and he has configured it all.

Information given from him:

• He has assigned me my RSA key to my email, and it is linked to my account.
• My SSH key is used in my profile section.
• I show up in the authorized_keys and in the repos.

He is able to create projects, commit, and push. However, I can do all of that except for pushing.

I have my global configuration correct (username and email), and I have set up everything according to what the project page will tell me:

mkdir project
cd project
git init
touch README
git add README
git commit -m 'first commit'
git remote add origin git@website.com:CoderMusgrove/project.git
git push -u origin master

Doing this, it starts to ask me for a password. There is no password. We have tried reconfiguring everything from the bottom, but we cannot seem to find the issue. He has reset all of my keys, and has given me all of his permissions. He is able to do everything on his end just fine.

At an older point in time, and at other times, it will say something about something failing, or being invalid. Such as a key being invalid, but we worked out that issue just fine. The first issue was when I would try to push a commit, and it will say that the repository didn't exist.

What is not allowing me to push commits, but he can, even though our accounts are configured exactly the same?

Edit
I attempted the command ssh -vvvT gitlab@localhost, replacing localhost with my host, and this is the output (HOST is the replacement of my host)

Answer 1

The issue that occurred was that the installation was corrupt, which made me fully have no permission. The issue has been solved with a re-installation.

Answer 2

Looks like your SSH key is invalid, try regenerating one, and adding it to your GitLab user account.

After that, you can re-push your commit
