Currently we provide binary packages for Ubuntu 12.04 LTS via the build repository
here on dengine.net. We also have a Launchpad PPA
that has the latest unstable version in both 32-bit and 64-bit variants.
In the sjke/doomsday PPA
, I've added a separate "doomsday-stable" package for the latest stable release. Making it separate was necessary because Launchpad only keeps the latest version of each package.
Our autobuilder can only support so many versions of Ubuntu at a time, so some changes will likely be done regarding the builder setup. Presently the builder is running a 32-bit 12.04, 64-bit 12.04, 64-bit 13.10, and 64-bit 14.04. However, if Launchpad were to be used for building the binary packages, our builder wouldn't need separate 32 and 64 bit versions. Also, we'll be dropping the older versions eventually, to make room for new ones. 13.10 is probably the first to go, as LTS releases should have priority.
At some point in the future I also plan to look into how the Launchpad-built binary packages could be integrated into our build repository.
