Update Debian familiy GNU/Linux with only packages that are allready in cache. Works on: Ubuntu, Canaima, Mint, LMDE, Sparky, Aptosid, etc.

sudo bash -c "apt-get upgrade -s |grep 'Inst '| cut -d' ' -f2| xargs -l1 apt-get install - --no-download"
Works for Debian an sons distros. With a bad internet connection sometime I download the updateable packages in another place, but I can't be there all time takes upgrade every packages... so I execute this for update only packages that are in Debian's apt cache. Using the 'sudo bash -c' for no asking every time apt-get need sudo permition.
