Generating SSH Keys

If you don't have ssh key, open terminal and run following commands:

Copycd ~/.ssh

^
ssh-keygen -t rsa -C "your_email@example.com"

When you have ssh key, just copy public part to clipboard:

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

To install xclip run:

Copysudo apt-get install xclip

Then add to GitHub or GitLab keys in profile settings
