So, it works.
Fresh install of Ubuntu 10.04LTS upgraded to 20.04, and the only third party tool I had to use was a gparted boot ISO, because I stupidly made the initial vmdk image far too small. 32GB should be your minimum; at 10GB you're going to hit capacity issues.
As per my advice to drook on Slack:
Ensure you have quite a lot of time set aside. This will take at least a couple of hours; quite a lot more if your storage is rotating rust and/or your network is embarrassingly slow
Ensure that you have at least 10GB spare disk space and/or do "apt-get clean" between versions; the upgrade is not stupid and checks first
I had to comment out the third-party repository in sources.list
If this machine is virtualised, consider removing the VirtualBox additions (other virtualisation solutions with similar auxiliary packages are available) - could have been coincidence, but I had a hard lockup at the GDM screen when upgrading 10.10 -> 11.04.
The order of releases it chooses is a bit weird at first - Mine went 10.04LTS, 10.10, 11.04, 11.10, 12.04LTS, 14.04.LTS (and so on) - just roll with it
Remember to pass the flags for saying "yes" to everything if you want this to be even slightly unattended-flavour
Also note you can give do-release-upgrade, which is very conservative by default, a kick by adding the "-d" option.
