[Bug 2091714] Re: packagekit noble update uninstallable on armhf, depends on libapt-pkg6.0t64 (>= 2.8.2) from proposed

[Andreas Hasenack]

Right, I was going to say you picked up apt 2.8.2 because of
packagekit's incorrect dependency. Sorry about that, and glad you got it
working again.

Title:
  packagekit noble update uninstallable on armhf, depends on libapt-
  pkg6.0t64 (>= 2.8.2) from proposed

Status in packagekit package in Ubuntu:
  Invalid
Status in packagekit source package in Noble:
  Fix Released

Bug description:
  [ Impact ]

  The noble packagekit update[1] to fix LP: #2086773 picked up those
  dependencies on armhf due to t64 mangling changes in the C++ symbols,
  and is now uninstallable:

  ubuntu at n-armhf:~$ sudo apt install packagekit
  Reading package lists... Done
  Building dependency tree... Done
  Reading state information... Done
  Some packages could not be installed. This may mean that you have
  requested an impossible situation or if you are using the unstable
  distribution that some required packages have not yet been created
  or been moved out of Incoming.
  The following information may help to resolve the situation:

  The following packages have unmet dependencies:
   packagekit : Depends: libapt-pkg6.0t64 (>= 2.8.2) but 2.7.14build2 is to be installed
  E: Unable to correct problems, you have held broken packages.

  The planned fix is to remove apt 2.8.2 from noble-proposed (done),
  rebuild packagekit (this bug), and release that.

  1. https://launchpad.net/ubuntu/+source/packagekit/1.2.8-2ubuntu1

  [ Test Plan ]

  On a noble armhf system, install packagekit from noble-proposed. It
  must not pull in other non-packagekit packages from noble-proposed.

  In addition to that, the noble excuses report[2] should be clean of
  errors and show no interdependencies preventing the release of
  packagekit.

  [ Where problems could occur ]

  This is a no-change rebuild. Like all SRUs, it's always built with the
  proposed pocket enabled, but this time the newer apt 2.8.2 is not
  there, so that dependency will not be picked up. That being said, the
  risk is the same that an unintended dependency from noble-proposed
  will be picked up, but the test plan specifically checks for that.

  [ Other Info ]

  This is fixing a regression introduced by the release of
  https://launchpad.net/bugs/2086773 to updates, where even though it
  was noticed that the excuses page was flagging packagekit to be
  depending on apt from proposed, it was incorrectly deemed irrelevant
  by me (@ahasenack) at the time.
