I downloaded autoQ3d which is a deb package and it shows in my directory but it says it can't find the package. What command should I be using to force the install?:(

You probably have to cd /home/<username>/Download folder and then run sudo apt-get install q3d. If you downloaded the package, it's probably in you download folder.

example:
john822@john822-desktop: cd /home/<your username>/Downloads <enter>
john822@john822-desktop: sudo apt-get install q3d

and see if that works.

I use Gnome as does Ubuntu and I'm assuming their download folder is named Downloads also.
