[Jeremy Bícha]

Today's Ubuntu Desktop 24.04 daily pending ISO fails on a system with network access. This error shows in the embedded terminal:

E: Clearsigned file '/var/lib/apt/lists/partial/_cdrom_dists_noble_Release' contains unsigned lines.
Nov 07 16:24:46 ubuntu subiquity_log.1832[4343]:
E: The repository 'file:/cdrom noble Release' provides only weak security information.
