How to See Information about a Installed Debian Package

I needed to see what version of mythtv was installed on my Ubuntu 14.04 server and what dependencies it requires. Here is the solution.

.deb packages are stored at /var/cache/apt/archives

View mythtv package name

#ls -l /var/cache/apt/archives/mythtv*

Display Package Version

# apt-show-versions mythtv

MythTV implements the following PVR features, and more, with a
unified graphical interface:

- Video compression using RTjpeg or MPEG-4
- Program listing retrieval using XMLTV
- Themable, semi-transparent on-screen display
- Electronic program guide
- Scheduled recording of TV programs
- Resolution of conflicts between scheduled recordings
- Basic video editing
This package will install a complete MythTV client/server environment on a
single system. If you are intended on using this as your only MythTV machine,
and this machine is already configured as a desktop, this package will get you
up and running switfly.
If you are intended on installing this on a standalone/non-desktop machine,
you should look into the metapackages available:
mythtv-backend-master (backend with a local database)
mythtv-backend (backend needing a remote database)
