install .deb locally

sudo dpkg -i /path/to/deb/file
sudo apt-get install -f

-f, --fix-broken
           Fix; attempt to correct a system with broken dependencies in place.

When dpkg installs a package and a package dependency is not satisfied,
it leaves the package in an unconfigured state and that package is considered broken.

The sudo apt-get install -f command tries to fix this broken package by installing the missing dependency.
