Install a local .deb file and its dependencies

To install a local deb file and its dependencies use apt, not dpkg:

sudo apt install ./foo-1.2.3.deb

You’ll automatically get all of the dependencies installed with the package. (dpkg doesn’t understand dependencies or repos, apt does.)

The leading ./, or a full or relative path to the deb file, is required. The path is what tells apt that it’s a local file.

Hope you find this useful.
