I tried to switch from a HTTPS to SSH repo using git. Below are the first commands I used.

Then, when I tried to add a branch to the staging area, I got the following messages:
I am not able to push anything or add any commits to git from my command line either. I get an error saying "could not read remote repository". Could someone please help me? What should I do now? I am new to git and I don't want to dig myself in a deeper hole!
