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. You have to include the path to the deb file or this will not work.
Hope you find this useful.
I was battling with dpkg skipping some debs and found this. Solved my problem and enabled me to finish my offline installer. Thanks. DXT2
