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

[Hans Joachim Desserud]

I have seen this a couple of more times over the years, but I recently
caught the same issue with chromium-browser. This is on 20.04, according
to `apt policy` the changes are

$ apt policy chromium-browser
chromium-browser:
  Installert: 83.0.4103.61-0ubuntu0.18.04.1
  Kandidat:   83.0.4103.97-0ubuntu0.20.04.1
  Versjonstabell:
     83.0.4103.97-0ubuntu0.20.04.1 500
        500 http://no.archive.ubuntu.com/ubuntu focal-updates/universe amd64 Packages
 *** 83.0.4103.61-0ubuntu0.18.04.1 100
        100 /var/lib/dpkg/status
     80.0.3987.163-0ubuntu1 500
        500 http://no.archive.ubuntu.com/ubuntu focal/universe amd64 Packages

However, the attached log is what update-manager display under technical
details -> changes. It seems to be the complete history of the chromium-
browser package.

Noticing now (from the output above), could this be related to my recent
upgrade from 18.04 to 20.04. In other words, when upgrading from an
-updates package in one series to a package from -updates in another
series the comparision is confused because the older version was newer
published in the newer series and thus it doesn't have a lower bound in
the changelog?

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:
  New
Status in chromium-browser package in Ubuntu:
  New
Status in update-manager package in Ubuntu:
  New

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://no.archive.ubuntu.com/ubuntu/ quantal-updates/main i386 Packages
          500 http://security.ubuntu.com/ubuntu/ quantal-security/main i386 Packages
   *** 1.49.0-3.1ubuntu1.1 0
          100 /var/lib/dpkg/status
       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.
