The Mythbuntu team provides additional update repositories for software shipped with Mythbuntu.  The packaging used to create these builds is identical to that being used for content in the Ubuntu archive. 
  • The MythTV-Updates repository will contain updated MythTV software. It is automatically built each day when there are upstream fixes available.

    The repositories will only get updates for the selected MythTV series. So if you add the MythTV 0.24 Updates repo, you would receive any updates that upstream release to the 0.24 series only.  To change to another series (such as 0.25), you will need to remove the MythTV updates repo and add the MythTV updates repo for the series you want.
Mythbuntu will provide MythTV builds based on the following rules (see Build Rules below). The graphic below also indicates what
MythTV versions are currently available for each release. You can find the available MythTV Updates repos here

To add the MythTV Updates repo

sudo add-apt-repository ppa:mythbuntu/<Repo Name>
sudo apt-get update

Example

To add the MythTV Updates repository for version 29.

sudo add-apt-repository ppa:mythbuntu/0.29
sudo apt-get update
