Then they wait a little to see if that small subset will swamp them with issues or not.

In the first case the company will release the update on their website because only a small subset of their users will update that way. Some also spread software updates like oil on water: you start small and it gradually expands further and further. Which means you just don't jump in immediately but you check the water first.

Lots of software companies use the swimming pool method for releasing updates. It depends on when you ask that question. I'll have to give it a whirl and see if it This update doesn't seem to come through the auto update mechanism in the previous TP release. The process I'd use would be similar to what is done for NetBSD, that uses a disk image for installation. ipsw file and convert it into a VMDK file. I wonder if I have QEMU installed I could take that. I also expect those to disappear once Jammy is released - that's what happened to Impish 21.10. The only Desktop installation ISOs that I've had luck with (and are currently available) are the pre-release ones for 22.04 LTS 'Jammy Jellyfish' as noted in the TP guide. For some reason Canonical doesn't seem to want to release an ISO of Ubuntu Desktop that's usable for installation on the Tech Preview. Personally I put the blame more on Canonical than VMware.

I've found that Ubuntu Server released aarch64 ISOs work fine on the Tech Preview, but it's then a pain to have to install all the graphical components you'd find in a desktop release. I assume you're trying to use Ubuntu Desktop. OK - when I hear UTM or QEMU being mentioned I immediately think of people trying to run x86_64 operating systems. Windows 7 圆4 on apple silicon UTM is too slow to be usable. UTM handles all the downloading and everything.
