Package: aptitude
Version: 0.6.8.1-2
Severity: wishlist
Dear Maintainer,
The followingAptitude::ProblemResolver::SolutionCost example is the
aptitude manual:
from removals + 2 * canceled-actions
I tried to weight removals-of-manual higher than other removals and came
up with the following rule:
aptitude -o Aptitude::ProblemResolver::SolutionCost='10 * removals - 9 *
removals-of-manual + canceled-actions' remove htop
Since a local metapackage depends on htop, the resolver started its
work. And threw the following errors:
E: Failed to parse the cost settings string: <none>:1:15: Expected EOF, got '-'.
E: Failed to parse the cost settings string: <none>:1:15: Expected EOF, got '-'.
A simpler, yet less practical SolutionCost value with which we were able
to reproduce the issue is:
aptitude -o Aptitude::ProblemResolver::SolutionCost='removals -
canceled-actions' remove htop
It would be nice if Aptitude::ProblemResolver::SolutionCost would also
support substraction.
