** Summary changed:
- Unsolvable LTSEnablementStack Mesa package dependency
+ Package resolver can't find *-lts-utopic package dependencies, aborts
** Description changed:
[Description]
- On 14.04.2 aptitude/APT determinates non-LTSEnablementStack Mesa packages
instead of *lts-utopic pendants as dependencies. This leads to unsolvable
conflicts with the already installed *lts-utopic packages.
+ On Ubuntu 14.04.2 with updated kernel and X stack (LTS Enablement Stacks)
package resolver fails to find *-lts-utopic package dependencies, aborts.

+ [Test case]
+ $ sudo apt-get -o debug::pkgproblemresolver=true install qtbase5-dev
+ (Log attached as apt.log)
[Workaround]
- [a]
- $ sudo aptitude install qtbase5-dev libgles2-mesa-lts-utopic
+ Manually resolve:
+ $ sudo apt-get install qtbase5-dev libgles2-mesa-dev-lts-utopic
- [b]
- $ sudo aptitude install -s freeglut3-dev libgl1-mesa-dev-lts-utopic
+ Possible catch all solution:
+ $ sudo apt-get install .*-dev-lts-utopic
+
+ [Speculation]
+ Control file of libgles2-mesa-dev-lts-utopic do look right:
+ http://debian-handbook.info/browse/stable/sect.package-meta-information.html
+
+ Guess APT just get overwhelmend by the possibilies and aborts before
+ finding the right one.
+
+ Is there some SAT-solver, which could conform? Aptitude's resolver fails, too.
+ Could control files be tweaked to make resolving easier?
+
+ [Possible affected packages]
+ Possible all packages which have dependencies on *-mesa-dev for which there's
an updated version in the LTS Enablement Stacks.
+ Roughly:
+ $ apt-cache rdepends .*-mesa-dev
