Sorry, forgot a few more:
$ ls /var/lib/apt/lists/
$ dpkg -s python
$ apt-cache policy python

Note: please get out of root mode & return to user mode. Old school or
not, there are differences between how the commands that we ask you for
react when in root (#) mode. So please only use user mode unless asked
to use root. Thanks.

Regarding apt-cache & dpkg (dpkg-query), these may help:
<http://manpages.ubuntu.com/manpages/lucid/man1/dpkg.1.html>

<http://manpages.ubuntu.com/manpages/lucid/man8/apt-cache.8.html>

I forgot about this one:

I'll need to spend some time reviewing & comparing to your problem.
