[SOLVED] SSH_AUTH_SOCK set by gpg-agent replaced after login

Hello.

I am trying to set up SSH agent as per instruction from wiki.

I created env file ~/.config/environment.d/80_gpg_agent.conf:

PINENTRY=pinentry-qt
SSH_AUTH_SOCK=${XDG_RUNTIME_DIR}/gnupg/S.gpg-agent.ssh

You can't set empty variables in systemd environment so I didn't set SSH_AGENT_PID.

Then, if I don't login into KDE session I have correct value for SSH_AUTH_SOCK:

SSH_AUTH_SOCK=/run/user/1000/gnupg/S.gpg-agent.ssh

But after I log into KDE session, it is ovewritten by this:

SSH_AUTH_SOCK=/run/user/1000/ssh-agent.socket

Since KDE doesn't have built-in SSH-agent I checked following:

• ssh-agent is not running

• there is no code that sets SSH_AUTH_SOCK in .bashrc, .profile, /etc/bash.bashrc, /etc/profile or /etc/profile.d/*

• there are no env variables in /etc/environment or ~/.config/environment.d/* besides one that I set for gpg-agent

• I use keepassxc that has embedded ssh-agent but I didn't add it to autostart and it is disabled

So, question is, where is it set and how do I stop this from overriding my env?

I apparently solved this issue.

After thorough examination I found out that ~/.pam_environment has override for SSH_AUTH_SOCK:

SSH_AUTH_SOCK=${XDG_RUNTIME_DIR}/ssh-agent.socket

Since it is marked as deprecated I didn't even thought it might be used.

Deprecated means that it will stop working at some point in the future and people should switch to an alternative while it still works.
