i have successfully downloaded a file, but the file does not open when in the folder, these are all .deb files and the icon is like a sealed box,

  • try sudo apt install /path/to/whatever.deb or right click on > Open With Software Install – doug Aug 31 '16 at 02:05
  • @doug Isn't it sudo dpkg -i /path/to/whatever.deb ? – chili555 Aug 31 '16 at 02:08
  • In 16.04 apt can resolve dependencies so it's a decent choice over dpkg which can't (- there are a few corner cases where apt won't work & dpkg is a potentially better choice – doug Aug 31 '16 at 02:11

The .deb file is an application install package. The sealed box you see is a visual showing it's a package.

You can install the package by double clicking on it.

When you double click the file, it should bring up the software center and give you a graphical interface with a button to click install.

You can also right click on the icon and choose the install program installer to run.

Alternately you can install a deb package from the commandline with:

$ sudo dpkg -i [packagename.deb]
