Mythbuntu is an official Ubuntu flavor focused upon setting up a standalone MythTV based Digital Video Recorder (DVR) system. It can be used to prepare a standalone system or for integration with an existing MythTV network. Unlike similar projects, Mythbuntu keeps close ties with Ubuntu and all development is given back to Ubuntu. This architecture allows simple conversions from a standard desktop to a Mythbuntu machine and vice versa. The development cycle of Mythbuntu mirrors that of Ubuntu.
Mythbuntu as a separate distribution will cease to exist. We will take the necessary steps to pull Mythbuntu specific packages from the repositories (17.04 and later) unless someone steps up to take these packages over. MythTV packages in the official repositories and the Mythbuntu PPA will continue to be available and updated at their current rate.
Mythbuntu uses the XFCE desktop. All unnecessary standard Ubuntu applications such as LibreOffice, Evolution, and a full Gnome desktop are not installed in a default Mythbuntu install. If at any time a user wants to, they can install ubuntu-desktop, kubuntu-desktop, or xubuntu-desktop and add a full desktop onto their installation. This can easily be done via the Mythbuntu Control Centre.
