To install a local
deb file and its dependencies use
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,
./, 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.
