I have a slow method of doing this that does not take virtual packages
such as mail-transfer-agent into account. In this, "foo", "bar", and
"baz" are arbitrary file names. The final output is to stdout and is
formatted as 1 package per line, in alphabetical order.

  dpkg --get-selections | grep -w install | sed -e s/[[:space:]].*// >\
  foo
  
  apt-cache show `cat foo` | grep ^Suggests | sed -e s/^Suggests:\ // \
  -e s/\(.*\)//g -e s/[,\|]//g > bar
  
  tsort bar | sort > baz
  
  grep -vf foo baz
