Um, no... Like Steve Reilly already said, apt-get update only updates
the package database. There is no need to simulate it, it won't 'update'
any packages on your system. If you are talking about that, the comand
that does that is 'apt-get upgrade' (or maybe better 'apt-get
dist-upgrade'). There is no need to simulate it either though, since it
will ask you should it begin or not - it writes out how many packages
will get upgraded, and if any new would be installed and obsolete ones
uninstalled; then it asks you to confirm it (Y/n), at which time you
simply hit 'n' if you don't want to do it.
