[Aptitude-devel] Bug#959869: aptitude: "aptitude why" should take Provides into account

[Vincent Lefevre]

Package: aptitude
Version: 0.8.12-3
Severity: wishlist

zira% aptitude why x11proto-core-dev
i   tk8.5-dev Depends x11proto-core-dev

but I can remove the package without breaking the dependency:

zira% apt remove -s x11proto-core-dev
NOTE: This is only a simulation!
      apt needs root privileges for real execution.
      Keep also in mind that locking is deactivated,
      so don't depend on the relevance to the real current situation!
