RSA SSH keys

If you already have an RSA SSH key pair to use with GitLab

ssh-keygen -o -f ~/.ssh/id_rsa

If you don't have an existing one, Create a new one 

Go to 

gitlab settings -> SSH keys -> Generate one -> Generating new SSH key pair -> 

ssh-keygen -o -t rsa -C "your.email@example.com" -b 4096

Adding a SSH key to your GitLab account

xclip -sel clip < ~/.ssh/id_rsa.pub

Paste -> Add key

Git global setup

git config --global user.name "name"
git config --global user.email "email"

Create a new repository

git clone <copy_ssh_key>

you can test your setup by running ssh -T git@example.com (replacing example.com with your GitLab domain) and verifying that you receive a Welcome to GitLab message.

If you get this error:-

sign_and_send_pubkey: signing failed: agent refused operation

Permission denied (publickey).

Try:-

$ ssh-add

$ ssh-add -l
