I don't know what you mean with triggering the pkgProblemResolver. The
pkgProblemResolver gets triggered by the first stage solver producing an
unsatisfiable system state due to Conflicts between packages marked for
install and tries to solve the package that has unsatisfied
dependencies.

The logs show an unsupported system configuration:

- dconf is being forced to the version from proposed
- dconf-service is not made available to the apt command

We generally cannot support unrestricted use of -proposed: The proposed
pocket may be uninstallable at any point; but what we certainly cannot
support is if you force a specific package like dconf from proposed but
then hide other relevant binaries that require the same version.

I don't see a bug here.

Title:
  pkgProblemResolver finds problems on default Ubuntu Desktop install in
  Noble+

Status in apt package in Ubuntu:
  Incomplete
Status in dconf package in Ubuntu:
  Incomplete

Bug description:
  Spinning this bug off of 2072586 because it's not strictly related to
  the dconf changes.

  On a default Noble install, apt's pkgProblemResolver (when triggered)
  finds unmet dependencies (full log attached as noble-desktop-
  breaks.txt):

  ```
  The following packages have unmet dependencies:
   libcanberra-pulse : Depends: pipewire-pulse but it is not going to be installed or
                                pulseaudio but it is not going to be installed
  E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
  ```

  After removing libcanberra-pulse, pkgProblemResolver attempts to
  remove many desktop packages (see attached noble-desktop-remove.txt).

  The libcanberra-pulse issue does not occur on Plucky, but
  pkgProblemResolver still attempts to remove many of the desktop
  packages.

  To reproduce, install from ISO from releases.ubuntu.com; dist-upgrade,
  and trigger pkgProblemResolver.

  I'm not sure if this is expected behavior or not but would like to
  confirm since removing the desktop seems like misbehavior.
