[libzypp] Applying solution selected by user.

I developing Packagekit’s zypper backend integration with Bonsole and daemonUI for interactively dependency handling. One think I cannot repair is … dependency handling. Everything looks well. User could get list of problems, select solutions, see new list of problems, select solution and packagekit reports progress correctly. Problem is: if I had select to remove some packages for resolve problems, it will not be removed from the system and new packages is installed.

I put code below:

 ProblemSolutionList::const_iterator it3;
    ResolverProblem problem = **it2;
    it3 = problem.solutions().begin();
    for (; it3 != problem.solutions().end(); ++it3) {
      if (get_full_resolution_text(**it3) == (*it).selected) {
        apply = true;
        ProblemSolution solution = **it3;
  if (apply)

Everything seems to work, but packages aren’t removed if it needs to be removed to install another package. I think I must do something additional to adding solvable to resolver. It’s hard, because when I add solution and call resolve libzypp function, function returns true.

I solved this problems.

Look how it working:

Please, test.
