[NCLUG] remove a 3rd party app -- can't seem to find it in packages

[Ryan J Nicholson]

Bill,

If you used a package manager or apt from the command line..look in
/var/cache/apt/archives, you should see some cached package files..

The 3rd party app may have installed under /opt. Take a look. If you
find any files that look like they belong to the package, then you
might try Bob and Aaron's suggestions to use dpkg to search the
package database.
