Do so with caution though I've seen some machines where that shortcut
were followed...lots of broken packages and no way to fix it. its better
to use apt-cacher or just update after you coppied the apt folder's files.
When working on a computer you have to know enough:
To fake what you don't know.
Google what you can't fake.
How (and when) to 'motivate' the computer to do what Google won't tell.
