Thank you for your help triaging this! This is from the source system.
It is possible that I upgraded from another LTS to 22.04.  I've only
used LTS releases.  See below for usrmerge installation output on the
source system.

Bug description:
  [Analysis]
  usrmerge was not essential on 22.04 and systems that upgraded to it may not have been converted, as it was only Recommended.

  We need to add quirks to ubuntu-release-upgrader to convert systems
  that are not yet merged by first installing the usrmerge package.

  [Original bug report]
  Doing upgrade from 22.04 -> 24.04 beta.
