Quoting this directly from serverfault,
Simple and easy solution: just specify the unwanted packages with an extra – after each of them.
In your case you could, apt-get install cron mail- sql-
Replace mail and sql with respective dependencies you don’t want to install
You can also use the -s option to be extra careful.
From the man-page,
-s, –simulate, –just-print, –dry-run, –recon, –no-act No action. Perform a simulation of events that would occur but do not actually change the system.
