Sadly, what was true on May 27 is true no longer. A fresh re-install of Ubuntu 25.04 Server to a microSD card using the Raspberry Pi Imager on Windows no longer works. I've tried several different Pi Zero 2 Ws and several different SD cards and none of them work.I've got Ubuntu Server 25.04 running on the Pi Zero 2 W and everything seems to be OK. It ships without any swapfile, so package installs via apt and gcc compiles can run the system out of memory, but after I added a swapfile the package installs and gcc compiles aren't any slower than they were on PiOS. That will keep me mostly up to date until PiOS trixie is ready.
By the way, the application is a command-line / TUI USB audio signal processing "appliance"; there won't be any desktop and there will be assembly code and kernel shenanigans when it's all done. No offense, pipewire.I probably won't mess with the Bluetooth stack; it has a reputation for latency and other things I don't want. As long as a "conventional" Linux with a recent kernel runs on it, I think I can avoid the need for cross-build tools.

The green LED flashes a few times and then it goes dark. The Ubuntu 24.10 Server image works, so my guess is that the was 25.04 image was rebuilt some time after my initial tests. But I can't find any documentation on where these images come from or how they are created, so at this point I'm flying blind.
Does anyone here know how I can troubleshoot this? Who builds the Ubuntu images - Canonical, Raspberry Pi, or a third party? Where are they stored on a Windows machine? Is there an alternative source?
