Marking as a duplicate of bug #2084610. Same upgrader failure on a 22.04
to 24.04 upgrade, this time on arm64 (linux 5.15.185-tegra). The
architecture difference is incidental but the upgrader's denylist
refusal logic is shared.

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade.

  The package 'update-manager' is marked for removal but it is in the 
  removal deny list. 

  If none of this applies, then please report this bug using the 
  command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If 
  you want to investigate this yourself the log files in 
  '/var/log/dist-upgrade' will contain details about the upgrade. 
  Specifically, look at 'main.log' and 'apt.log'.
