I’ve set services.yubikey-agent.enable to true. However, even after rebooting I’m getting the following error message:
> ssh-add -l
Error connecting to agent: No such file or directory
Here is the output of some commands which I executed afterwards:
> systemctl --user status yubikey-agent.service

Any ideas what I’m doing wrong?
EDIT (1): Ok, if my research is correct it seems like that keyring/ssh is coming from gnome-keyring but in nix repl I’m getting this:
nix-repl> nixosConfigurations.pc.config.home-manager.users.tornax.services.gnome-keyring.enable
false
funny enough, I always wondered why I had a “keyring” app installed on my system after an update but it never bother me… unless now
