I just installed Ubuntu yesterday; when i ssh to github, rather than being prompted for a password, it just stalls. The command i entered was:
ssh -T [email protected]
After entering, the cursor blinks but nothing comes up. I've tried using the key on my friend's laptop; he gets a permission denied error message, meaning there is different behavior on different machines.
For reference, I'm running a Lenovo Ideapad 530s.
