Comment 1 for bug 2064959

I'm requesting an SRU:

  https://wiki.ubuntu.com/StableReleaseUpdates

[ Proposed solution ]

The original bug report and its solution are described here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1067398

* Update mrbuild to >= 1.9-2 to fix the build issue that caused mrcal to be deleted

* Build and include the omitted source packages:

  * mrcal gl-image-display

[ Impact ]

 * The deleted packages mrcal, gl-image-display will be available in 24.04

[ Test Plan ]

 * The affected packages have no rdepends

 * The "mrbuild" package does have a build-rdepends:

   * mrcal
   * gl-image-display
   * libdogleg
   * mrgingham
   * vnlog

   And none of these have any rdepends or build-rdepends outside of this set

 * Testing would mean confirming that the updated mrbuild can still be used to build the above packages. This will work, since the update to mrbuild is tiny, and is verified functional in Debian

[ Where problems could occur ]

 * The proposed solution adds two deleted source packages, and updates one (mrbuild). Thus the mrbuild update is the only thing that could possibly break anything

 * Because of the limited depends and rdepends, the implications are limited to the above-listed set of packages. mrbuild is the build system. If the above packages build successfully with the updated mrbuild, and their tests pass, we can declare victory.

[ Other Info ]

 * As described in the mailing list thread above, these packages weren't excluded because there was anything specifically wrong. The problem has been fixed for weeks in Debian when the Ubuntu FTBFS bug came through, and the only reason for the exclusion is the rush to meet the release deadline.
