I\'ve been trying for the last 2 hours. I\'m using xp-dev as a git repository provider (because I\'m already paying and I have svn repo over there) I\'ve given xp-dev my public
I faced this issue now. I was able to get the solution via the following link from GitExtension itself.
PuTTy and Github
Same would also work of GitLab. You will need to add generated ppk file to GitHub or GitLab under settings page.
It is pretty easy to do this with Git-Extensions;
GitExtension ask to load private key only if you use Putty. You should do it manually for OpenSSH like described for GitHub https://help.github.com/articles/generating-ssh-keys
I had this issue because I generated a SSH key with ssh-keygen and tried to use it with GitExtensions which only understands OpenSSH keys.
What you have to do is, from GitExtensions:
mykey.ppk
You should now able to use this new .ppk file in GitExtensions!
