SSH

As I’m almost exclusively using gpg-agent for SSH (except some cases where I use FIDO2 and resident keys), as a substitute for ssh-agent, I have to set it up, so other applications can connect to it.

For that we mainly have to unset SSH_AGENT_PID and set SSH_AUTH_SOCK. This is best done in our ~/.bashrc

~/.bashrc

unset SSH_AGENT_PID

if [ "${gnupg_SSH_AUTH_SOCK_by:-0}" -ne $$ ]; then
  export SSH_AUTH_SOCK="$(gpgconf --list-dirs agent-ssh-socket)"
fi

Tip

As we want to use git over ssh in a second anyway, we can test if everything worked by trying to connect to GitHub (of course, you already need ssh to be setup for your GitHub account)

ssh -T git@github.com

Dotfiles

Now that SSH is working just fine, we can switch the remote of the dotfiles repo over to use SSH.

~/dotfiles

jj git remote set-url origin git@github.com:DustVoice/dotfiles.git

A simple

jj git fetch

should now succeed without any issues.
