I did exactly what it said in this page:

https://www.raspberrypi.org/blog/buster-the-new-version-of-raspbian/

and thought that running "sudo apt dist-upgrade" worked somewhat
differently to the Jessie -> Stretch upgrade - in particular because dist-
upgrade promptly pulled down a large selection of packages before
installing them (with periodic questions about how I wanted deal with
several specific packages), before completing the process with a reboot.
This is similar to the in-situ version upgrade that Fedora has used for
the last five years, i.e. not like the Wheezy->Jessie and Jessie->Stretch
upgrades, which IIRC were just a rather larger update and without an
immediate reboot being required.
