[Bug 1797662] Re: advpng built from an archive without a .version file

[Hans Joachim Desserud]

Thank you for reporting this issue and help making Ubuntu better.

I can confirm that advancecomp 2.1-1 reports version "vnone" on Ubuntu
Cosmic as well.

When reporting bugs in the future please use apport by using 'ubuntu-
bug' and the name of the package affected. This will automatically add
useful debug information such as which package version and Ubuntu
release you are running. You can learn more about this functionality at
https://wiki.ubuntu.com/ReportingBugs.

** Changed in: advancecomp (Ubuntu)
       Status: New => Confirmed

** Tags added: bionic cosmic

  When running `advpng --version` its output does not provide the version of the utility. Instead it reports it as "vnone". Example:

  ```
  $ advpng --version
  advancecomp vnone by Andrea Mazzoleni, http://www.advancemame.it
  ```

  I expect it to return "v2.1-1". A la -

  ```
  advancecomp v2.1-1 by Andrea Mazzoleni, http://www.advancemame.it
  ```

  After some looking around it seems that maybe the wrong archive is
  fetched before building it. Possibly
  https://github.com/amadvance/advancecomp/archive/v2.1.tar.gz

  Instead it should be
  https://github.com/amadvance/advancecomp/releases/download/v2.1/advancecomp-2.1.tar.gz.
  The one that was used is an archive of the git repository which does
  NOT contain the `.version` file, and latter one linked is a release
  archive which I think is created from repository after running all
  auto* tools and running the script that generates .version file.

  This is all information gleaned from the image_optim project where
  there is more information in an issue there:

  Much thanks to Ivan Kuchin and Kasper Grubbe over there helping track
  this down.
