title: cloning a repository in gitkraken from url ssh invalid
body: <p><br>
  I'm quite new to Linux and I have some trouble using GitKraken (in Windows I use SourceTree). I want to clone a repository that is on my NAS. Unfortunately, when I try to clone it says: "Configured SSH key is invalid. Please confirm that it is properly associated with your Git provider". In Preferences>Authentication I have checked (default) Use Local SHH agent.<br>
  If I clone the rep from the terminal with git clone command it asks for the password and everything is ok.<br>
  Any suggestion?<br>
