Comment 8 for bug 997371

There are multiple deb-src not added reports open (#399771, #301602), so the issue must be coming from there, as I have just used the methods of the existing software-properties code. Anyway, I will propose a merge for this tool, as you have reported it basically works, and will take a look at the deb-src issue a bit later. Thanks for your feedback, I hope the tool will come handy.
