Do not abort failed local install when dpkg -i fails, only after the apt-get install -f fails
otherwise missing dependencies will never get installed
only call fix-missing when dpkg -i fails
we need to call "apt-get install -f" to fix missing dependencies from failed dpkg -i,
--fix-missing does not install missing deps.
