|Q||In trying to checkout a repository from github using cygwin (unix like command line interface for windows), according to the github help is do a ssh email@example.com. However, I got a “Permission denied (publickey)”.|
|A||The missing ingredient for me was that cygwin uses the HOME environment variable and this was not set on my machine. I was then able to do a
git clone firstname.lastname@example.org:<github repository>.
