Answer 1

I encountered this same problem, however the GIT_SSH solution appeared to work once for me. After a computer restart I realized it was something else, as I was able to clone my private repositories with no problem using Git Bash or Command Prompt, but not in Sublime Text 3 with the SublimeGit plugin. My solution was simple and is actually what @BlueRaja - Danny Pflughoeft mentioned but I thought it could use some direction ;)

Basically you just need to edit ~/.ssh/config and ensure the username is git. You can also tell it to use a specific SSH key for Github -- My ~/.ssh/config file looks like the following:

Host gh
    Hostname github.com
    User git
    IdentityFile ~/.ssh/github_rsa.pub

I have a specific key for Github due to the number of other things I do throughout my day, but if you've only got one then it usually will be ~/.ssh/id_rsa.pub like Github explains here.

I know everyone has a different solution, but I'll leave this here for anyone who may encounter this article without a fix. Good luck!
