Title:
  incorrect problem resolution

Status in “aptitude” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: aptitude

  Aptitude will incorrectly handle the following situation.  Let's say I
  have package A and package A-extensions installed.  Package A
  recommends package A-extensions.  Package A-extensions always depends
  on the same version of A as itself.  Currently, both A and
  A-extensions are at version 1.1.  The upstream repo has 1.2 of A, but
  is still at 1.1 of A-extensions.

  If there are other packages to be updated, aptitude will (correctly
  IMHO) suggest to hold both A and A-extensions at 1.1.  That is fine.
  If there are no other packages to be updated (after all other packages
  have been updated), aptitude's only automatic solution is to remove
  A-extensions.  That is definitely wrong, since keeping both packages
  at the installed version resolves the problem just fine.  IMHO, this
  is also preferred over needlessly removing a package.
