You may encounter the following error when you try to access GitHub via SSH on Linux:
ssh -vT email@example.com # ... # 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 simply loading your keys into your SSH agent with
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
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)
