Solution 1:

The rabbitvcs package is within the official repositories so remove the ppa's again and make sure your /etc/apt/sources.list looks like this. Then do:

sudo apt-get install rabbitvcs*

If you run into following error:

IOError: [Errno 13] Permission denied: '/home/username/.config/rabbitvcs/settings.conf 

simply correct the permissions by :

sudo chown "$USER" .config/rabbitvcs -R
