This bug was fixed in the package ubuntu-release-upgrader - 1:24.04.16

---------------
ubuntu-release-upgrader (1:24.04.16) noble; urgency=medium

  [ Nathan Pratta Teodosio ]
  * DistUpgrade: readfp was replaced by read_file in configparser.
    (LP: #2062435)

  [ Nick Rosbrook ]
  * Run pre-build.sh: updating mirrors, demotions, and translations.
