usage this laptop might frequently be on LANs that must be considered

The meme that "the Ubuntu default install does not run daemons that
listen to the outside" is not strictly true: it runs Avahi. "Avahi is a
system which facilitates service discovery on a local network. This
means that you can plug your laptop or computer into a network and
instantly be able to view other people who you can chat with, find
printers to print to or find files being shared" (

It also runs dhcp and it runs a kernel that faces network traffic. Add
to that Firefox, any filesharing programs you might run, etc.

I don't know about you, but I'd find an unpatched known remote hole in
my kernel or avahi not tolerable.

If you do disable updates you should at least subscribe to
ubuntu-security-announce and read what alerts come up:

I'd recommend not to disable upgrades but apply them selectively. The
Update Manager or your favorite command line frontend to APT let you do
