[Bug 1132472] Re: Update-manager list earlier changes for certain packages before the relevant change for the update in question

[Olivier Tilloy]

And I can reliably observe the issue in a focal VM where I installed the
chromium-browser package from bionic. Update-manager offers the update
to the newer version in focal, and the changelog textbox displays the
entire changelog since the first version of the package.

This might be caused by the versioning scheme used to update chromium in
stable releases. But it's really a bug in update-manager.

Title:
  Update-manager list earlier changes for certain packages before the
  relevant change for the update in question

Status in boost-defaults package in Ubuntu:
  Invalid
Status in chromium-browser package in Ubuntu:
  Invalid
Status in update-manager package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce:
  1. Have an old version of some boost package when a newer version is available.
  2. Open update-manager, select the boost package and look at the "Changes" tab.

  Expected result:
  The tab should contain which version I have currently installed, which version is available, and a section from the changelog summarizing the changes between those two versions.

  Actual result:
  While the boost packages have this, it is far down below a series of older changelog entries. All of these are for versions older than the one currently installed and as such are already included in the version I have. Furthermore they push down the "currently installed/available version" part which should always be listed at the top.

  I am not sure why this happens, and why it only happens with boost
  packages. I have seen this before with a previous boost update
  (unfortunately I failed to file a bug before updating), but not in any
  other packages.

  $ apt-cache policy libboost-date-time1.49.0
  libboost-date-time1.49.0:
    Installed: 1.49.0-3.1ubuntu1.1
    Candidate: 1.49.0-3.1ubuntu1.2
    Version table:
       1.49.0-3.1ubuntu1.2 0

          500 http://security.ubuntu.com/ubuntu/ quantal-security/main i386 Packages
   *** 1.49.0-3.1ubuntu1.1 0

       1.49.0-3.1ubuntu1 0
          500 http://no.archive.ubuntu.com/ubuntu/ quantal/main i386 Packages

  With the package above installed, this issue should be easy to
  reproduce. I have also attached the content of the "Changes" tab in
  update-manager.
