Using VPS SSH with GitHub?

Question

SSH

Please tell me:

I made the keys under the root in my homework. I added them via
eval $(ssh-agent -s)
ssh-add test_vps_net
for wiretapping, then added a public key (root) to github, and now:
1) I use ssh -T [email protected] from root - it works
2) I use from another user the same, only with sudo - DOES NOT WORK (permission denied public key)

in theory, if you use it with sudo, then it should be taken from the root's home folder, and there is just this key ..
