 Do not use `sudo make install` - this will bypass the apt package manager and possibly cause trouble. Instead, package this for your distribution following the guidelines and best practices of that distro. If building for Ubuntu, we recommend using either `debuild` (if working on Ubuntu packages is something you do rarely and you want something that's quick to set up) or `sbuild` (if you need to build packages all the time).
