** Description changed:

  There is an issue where old package versions are getting released for
  newer Ubuntu releases without properly updating the shared-library
  references. This causes regressions where a package that worked in
  previous versions starts to fail with an error like:
  
  photoprint: error while loading shared libraries: libgutenprint.so.2:
  cannot open shared object file: No such file or directory
  
  The underlying issue seems to cause reappearing bugs like bug #260849,
  where the photoprint package refers to libgutenprint.so.2 (the file in
  current Ubuntu releases is libgutenprint.so.3).
  
  This was discussed in Ask Ubuntu chat:
- http://chat.stackexchange.com/rooms/201/conversation/bug-1120870

  What we guess is happening is that when a new Ubuntu release appears,
  binary packages with no source changes are copied unmodified into the
  newer Ubuntu repository. It apparently does not check that the package
  still works, or specifically that needed shared libraries still exist.
  What should happen is that the package gets rebuilt when needed (simply
  rebuilding the package gets it to work again:
