OK, once launchpad is done with the last publish, I hope, my PPA is ready for first tests:
has packages for Ubuntu 24.04 with the newer libcamera from the RaspiOS as well as the Hailo packages natively built for Ubuntu/Python 3.12 … 
Tests with my setup (Pi5 + Arducam PiCam v3-w-AF + AI-Hat+) worked as expected. But I don’t make any claims. The source packages are also all there. Feel free to fix issues, you find, and send patches. I do this as a hobby and I don’t have a big test farm, so I can probably not reproduce very specific issues.
One comment: Make sure, the user, which is using libcamera/rpicam-* and friends has to be a member of the video group! That’s one group, not added by default!
I hope, this helps somebody Have fun exploring
