I’m surprised that Python-3.14 is required for V15 head or V16. Isn’t the latest Debian stable supported which comes with Python-3.13?
I’m also surprised that there does not seem to be a Trixie install guide. Docker is the worst (security audit wise whether manual or e.g. runzero).
I’m especially surprised because I tried an upgrade from Debian 12 to 13 with v15 head maybe 6 months or a year ago and it had packages which were too new and I had to restore from backup to Debian 12.
