I am setting up Git usage on Raspbian. This worked OK:

   cd .ssh
   ssh-keygen -t rsa -b 4096 -C "[email protected]"
   eval $(ssh-agent -s)
   ssh-add ./id_rsa_rpi

After I created the keys locally, I went to GitHub and added a public key there. It all worked OK, I cloned a few repositories without problems. Confirmed it all with ssh -vT [email protected]

However, after a shutdown yesterday and a powerup today, git pull didn't work: [email protected]: Permission denied (publickey).

I had to repeat the following:

eval $(ssh-agent -s)
ssh-add .ssh/id_rsa_rpi

Now it works again.

How do I make this permanent?

  • I hope that you didn't create your key w/o a password. And in that case you'll always need to authenticate ... depending on your desktop/window manager you should be able to a) automatically run eval $(ssh-agent -s) during its startup, which will then give you session info in all subprocesses.

I guess that as your key is not named with default name 'id_rsa', git has to know which one to use.

    Yes, according to the ssh manpage, The default is ~/.ssh/id_dsa, ~/.ssh/id_ecdsa, ~/.ssh/id_ed25519 and ~/.ssh/id_rsa. Ssh-agent is a process (daemon) which can manage keys, but as a process, dies when you reboot. Commented Nov 11, 2021 at 11:25
