Cannot install apt-install in Ubuntu 16.04 "waiting to install "

I'm having the same issue with Ubuntu Software with Ubuntu 16.04, but I found an easy GUI workaround in the meantime via "GDebi Package Installer" so you don't have to fiddle around with CLI with all your .deb packages and it'll capture all the dependencies so you don't have to worry about forcing apt-get installs.

1. run "sudo apt-get install gdebi"
2. In Nautilus, right-click your .deb file and select "Open With" -> "GDebi Package Installer"
3. Select "Install Package" to install.
