Version in PKG-INFO says "UNKNOWN" instead of "2.0.5"

[Realgo Sysadmin]

If setup.py lists a dependency on python-daemon with a version number, checks for that version will fail because the python-daemon PKG-INFO file reports "UNKNOWN" as the version. This can be seen in the file list on the ubuntu packages site:

http://packages.ubuntu.com/xenial/all/python-daemon/filelist

Which includes:

[...]
/usr/lib/python2.7/dist-packages/python_daemon-UNKNOWN.egg-info/PKG-INFO
/usr/lib/python2.7/dist-packages/python_daemon-UNKNOWN.egg-info/dependency_links.txt
/usr/lib/python2.7/dist-packages/python_daemon-UNKNOWN.egg-info/not-zip-safe
/usr/lib/python2.7/dist-packages/python_daemon-UNKNOWN.egg-info/requires.txt
/usr/lib/python2.7/dist-packages/python_daemon-UNKNOWN.egg-info/top_level.txt
/usr/lib/python2.7/dist-packages/python_daemon-UNKNOWN.egg-info/version_info.json
[...]

This seems to be fixed in Yakkety:

http://packages.ubuntu.com/yakkety/all/python-daemonize/filelist

Which includes:

[...]
/usr/lib/python2.7/dist-packages/daemonize-2.3.1.egg-info/PKG-INFO
[...]
