Hi jms209,
Welcome to LQ!
If you want to remove all files for a package you use:
Code:
$ apt-get remove package --purge
The 2 files removed might possibly actually be "2 packages removed". 2 not updated just means there is an update for 2 packages, but you didn't update them.
You don't necessarily need to update unless you want some certain new feature in a certain package. If a package won't install all the way it's usually a bug in the packaging (incorrect dependencies, etc.). So, you can make a bug report for the package.
Or you can do what most newbies do: wait a week or two until someone else has made a report and the problem is fixed.
Or, you can try manually retrieving the package file from a mirror and use
Code:
$ dpkg -i --force-depends full_file_name_of_package
And that still might fail, but it's sometimes the only way!
Also, when you install a package(s) the package files are stored in
Code:
$ /var/cache/apt/archives/
You can run the above command from that directory. I think Mint automatically installs sudo.
