[Bug 2147213] Re: [resolute] Unsupported platform 'Raspberry Pi 4 Model B Rev 1.2'.

[arQon]

Another noble->resolute failure here, also a 4B Rev 1.2. flash-kernel is
still installed but (obv) now fail; and piboot-try is absent.

$ apt policy piboot-try
piboot-try:
  Installed: (none)
  Candidate: 1.1ubuntu0.1
  Version table:
     1.1ubuntu0.1 500
        500 http://ports.ubuntu.com resolute/main arm64 Packages

Interestingly, and I assume "unexpectedly to you":
  $ grep piboot /var/log/dist-upgrade/*
  $

and
  $ grep flash-ker /var/log/dist-upgrade/*
/var/log/dist-upgrade/screenlog.0:Preparing to unpack …/288-flash-kernel_3.110ubuntu2_arm64.deb…
/var/log/dist-upgrade/screenlog.0:Unpacking flash-kernel (3.110ubuntu2) over (3.107ubuntu13~24.04.6)…
/var/log/dist-upgrade/screenlog.0:Setting up flash-kernel (3.110ubuntu2)…
/var/log/dist-upgrade/screenlog.0:flash-kernel: deferring update (trigger activated)
pi ~ $ 

I had to tail the flash-kernel results since the previous line was the
entire dist-upgrade package list, but this seems informative: it's not
that it *failed* to swap the package out, it simply didn't even think it
*should* (judging by the lack of a Remove entry), let alone actually try
to.
