When trying to SSH into GitHub.com on a Linux computer, you may see the following message in your terminal:
$ ssh -vT firstname.lastname@example.org > ... > Agent admitted failure to sign using the key. > debug1: No more authentication methods to try. > Permission denied (publickey).
For more details, see this issue report.
You should be able to fix this error by loading your keys into your SSH agent with
# start the ssh-agent in the background $ eval "$(ssh-agent -s)" > Agent pid 59566 $ ssh-add > Enter passphrase for /home/you/.ssh/id_rsa: [tippy tap] > Identity added: /home/you/.ssh/id_rsa (/home/you/.ssh/id_rsa)
If your key does not have the default filename (
/.ssh/id_rsa), you'll have to pass that path to
# start the ssh-agent in the background $ eval "$(ssh-agent -s)" > Agent pid 59566 $ ssh-add ~/.ssh/my_other_key > Enter passphrase for /home/you/.ssh/my_other_key: [tappity tap tap] > Identity added: /home/you/.ssh/my_other_key (/home/you/.ssh/my_other_key)
