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 appropriate init file

Nushell

Nothing to do, since it’s already included in my dotfile’s ~/.bash_profile.

Xonsh

~/.config/xonsh/user.xsh

if "SSH_AGENT_PID" in ${...}:
    del $SSH_AGENT_PID

if ($gnupg_SSH_AUTH_SOCK_by if "gnupg_SSH_AUTH_SOCK_by" in ${...} else 0) != os.getpid():
    $SSH_AUTH_SOCK = $(gpgconf --list-dirs agent-ssh-socket)

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.

native

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

jujutsu

~/.local/share/chezmoi

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

A simple

native

chezmoi update

jujutsu

~/.local/share/chezmoi

jj git fetch

should now succeed without any issues.
