The problematic package is ruby-activesupport-2.3 which gets a higher score (score=21) than ruby-activesupport (score=11) (probably due to a high number of rdepends in wheezy, the scoring seems to be fixed in jessie though): Investigating (0) ruby-activesupport [ amd64 ] < none -> 2:4.1.7-1 > ( ruby ) Broken ruby-activesupport:amd64 Breaks on ruby-activesupport-2.3 [ amd64 ] < 2.3.14-7 > ( ruby ) Considering ruby-activesupport-2.3:amd64 21 as a solution to ruby-activesupport:amd64 11 Holding Back ruby-activesupport:amd64 rather than change ruby-activesupport-2.3:amd64 and this starts a cascade of keeping the *-2.3 packages installed, resulting in the old rails being kept. So add a transitional dummy package that ensures the stack of *-2.3 packages gets removed: Package: ruby-activesupport-2.3 Architecture: all Depends: ruby-activesupport (>= 2:4), ${misc:Depends}, ${shlibs:Depends} Breaks: ruby-activesupport-3.2, ruby-activesupport-4.0, ruby-actionpack-2.3, ruby-activerecord-2.3, ruby-activeresource-2.3, ruby-rails-2.3, Description: transitional dummy package Ensure the removal of rails 2.3 on upgrades from wheezy. This package can be safely removed. and in ruby-activesupport use Replaces: ruby-activesupport-2.3 (<< 2:4), ruby-activesupport-3.2, ruby-activesupport-4.0 Breaks: ruby-activesupport-2.3 (<< 2:4), ruby-activesupport-3.2, ruby-activesupport-4.0 It's important to have the Breaks directly in ruby-activesupport-2.3, having them only transitively via ruby-activesupport does not work - that seems to be the apt bug fixed in jessie. The upgrade then looks like this: Investigating (0) ruby-activesupport-2.3 [ amd64 ] < 2.3.14-7 -> 2:4.1.7-1 > ( ruby ) Broken ruby-activesupport-2.3:amd64 Breaks on ruby-actionpack-2.3 [ amd64 ] < 2.3.14-5 > ( ruby ) Considering ruby-actionpack-2.3:amd64 5 as a solution to ruby-activesupport-2.3:amd64 22 Added ruby-actionpack-2.3:amd64 to the remove list Broken ruby-activesupport-2.3:amd64 Breaks on ruby-activerecord-2.3 [ amd64 ] < 2.3.14-6 > ( ruby ) Considering ruby-activerecord-2.3:amd64 9 as a solution to ruby-activesupport-2.3:amd64 22 Added ruby-activerecord-2.3:amd64 to the remove list Broken ruby-activesupport-2.3:amd64 Breaks on ruby-activeresource-2.3 [ amd64 ] < 2.3.14-3 > ( ruby ) Considering ruby-activeresource-2.3:amd64 1 as a solution to ruby-activesupport-2.3:amd64 22 Added ruby-activeresource-2.3:amd64 to the remove list Broken ruby-activesupport-2.3:amd64 Breaks on ruby-rails-2.3 [ amd64 ] < 2.3.14-4 > ( ruby ) Considering ruby-rails-2.3:amd64 -1 as a solution to ruby-activesupport-2.3:amd64 22 Added ruby-rails-2.3:amd64 to the remove list Fixing ruby-activesupport-2.3:amd64 via remove of ruby-actionpack-2.3:amd64 Fixing ruby-activesupport-2.3:amd64 via remove of ruby-activerecord-2.3:amd64 Fixing ruby-activesupport-2.3:amd64 via remove of ruby-activeresource-2.3:amd64 Fixing ruby-activesupport-2.3:amd64 via remove of ruby-rails-2.3:amd64 Investigating (0) ruby-actionmailer-2.3 [ amd64 ] < 2.3.14-3 > ( ruby ) Broken ruby-actionmailer-2.3:amd64 Depends on ruby-actionpack-2.3 [ amd64 ] < 2.3.14-5 > ( ruby ) (>= 2.3.14) Considering ruby-actionpack-2.3:amd64 5 as a solution to ruby-actionmailer-2.3:amd64 1 Removing ruby-actionmailer-2.3:amd64 rather than change ruby-actionpack-2.3:amd64 Done The transitional package now causes a cascade of removals, not keeps :-) (the score increased by one because the package now exists in the target release) The following packages will be REMOVED: ruby-actionmailer-2.3 ruby-actionpack-2.3 ruby-activerecord-2.3 ruby-activeresource-2.3 ruby-rails-2.3 ... It's sufficient to have only one transitional package - the one that gets the highest score from apt.
