[Bug 2099829] Re: libcanberra-gtk3-0t64 still around in oracular/plucky

[Julian Andres Klode]

** Description changed:

  [Impact]
  People upgrading from noble are stuck on the no-longer-available libcanberra-gtk3-0t64 (which has been changed back to libcanberra-gtk3-0 in oracular).
  
  This is in turn causes them to have an unsupported package installed,
  and the new apt solver is producing a "worse result" because it notices
  and tries to replace it.
+ 
+ [Test plan]
+ Upgrade from noble to oracular or take an upgraded system, run apt dist-upgrade and see libcanberra-gtk3-0 being installed.
+ 
+ [Where problems could occur]
+ There could be typos or something in theory. The solver could go mad in anger. But it seems pretty unrealistic.
  
  [Other info]
  The transitional package is Architecture: any and Multi-Arch: same to force the upgrade across architectures, it can't be Architecture: all as then it would only enforce the upgrade for the native architecture.
  
  [Original bug report]
  
  The error appeared during an attempt to install supertuxkart

Bug description:
  [Impact]
  People upgrading from noble are stuck on the no-longer-available libcanberra-gtk3-0t64 (which has been changed back to libcanberra-gtk3-0 in oracular).

  This is in turn causes them to have an unsupported package installed,
  and the new apt solver is producing a "worse result" because it
  notices and tries to replace it.

  The issue for oracular users meanwhile is the lack of security support
  for the t64 package they are stuck on, in case a security update
  happens.

  [Test plan]
  Upgrade from noble to oracular or take an upgraded system, run apt dist-upgrade and see libcanberra-gtk3-0 being installed.

  [Where problems could occur]
  There could be typos or something in theory. The solver could go mad in anger. But it seems pretty unrealistic.
