I wonder whether it could be better to increase the value of Aptitude::ProblemResolver::Remove-Level. Option: Aptitude::ProblemResolver::Remove-Level Default: 10000 Description: The safety cost assigned to actions that remove a package. See the section called “Safety costs” for a description of safety costs. But I fear that if Aptitude skips low-cost solution with SolutionCost "removals", it will also skip them with an increased Remove-Level (unless the decisions related to safety cost levels are privileged in the heuristics). -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
