Configure sudo to keep SSH_AUTH_SOCK

Question

What's the proper way to configure sudo to keep the SSH_AUTH_SOCK environment variable?

I was following some guide on the Internet, but it is not working for me:

$ printenv | grep SSH
SSH_AUTH_SOCK=/tmp/ssh-Zy2v8uDtJxPw/agent.2628
SSH_AGENT_PID=2629

$ sudo printenv | grep SSH | wc 
      0       0       0

I thought I need to restart sudo service, but How To Restart Sudo Service on Ubuntu 16.10 says no need.

Check out the `env_keep` option in `/etc/sudoers` (`man sudoers`). — Gunnar Hjalmarsson, Aug 08 '19 at 07:50
I know the env_keep option and I've added SSH_AUTH_SOCK, but it is not working, without restarting Sudo Service, as seen in OP. Your comment doesn't provide much help I'm afraid, @GunnarHjalmarsson. Have you actually tried it before your reply? — xpt, Aug 08 '19 at 12:02
It was sad that pointing at the documented way to do it wasn't helpful. Good luck! — Gunnar Hjalmarsson, Aug 08 '19 at 12:19
That's a very weird way to show being helpful. Guess how many git questions are asked on stackoverflow, despite there are _"documented way to do it"_, then check out if your guess was close enough at https://stackoverflow.com/questions/tagged/git — xpt, Aug 08 '19 at 12:46

sudo -E printenv | grep SSH

-E Preserves your environment variables into the sudo.
