Answer 1

In my case I had this problem with GitLab because I was working with non-default SSH key pair paths. @NEO 's answer works perfectly:

ssh-add ~/.ssh/other_id_rsa

However, I had to do this everytime that I opened a new terminal.

To make this change permanent, you have to edit ~/.ssh/config and add the following:

Host gitlab.company.com
RSAAuthentication yes
IdentityFile ~/.ssh/config/private-key-filename

For more detailed info check gitlab's documentation.

Answer 2

If you haven't already read it, you should look through the GitHub help page for this error:

Error: Permission denied (publickey)

Every time that I've had this problem, it was due to the last issue listed on that page: I didn't have the public key from my current workstation attached to my GitHub account. Of course, GitHub also provides instructions on how to attach your public key to your account.

tl;dr

Make sure your current public key is attached to your GitHub account.

Answer 3

I had the similar problem and my problem was solved by running the following command to add my key to the list of known keys:

ssh-add ~/.ssh/id_rsa

Hope it solves yours too. ;)
