ValueError: Old and New apt format defined with unequal values True vs False @ apt_preserve_sources_list

Thats the error.
MAAS or the user sent configuration that had
 apt_preserve_sources_list: True
and
 apt:
   preserve_sources_list: False

Those are the same setting in 'Old' and 'New' config format. Cloud-init can't determine which one you meant, so it raised exception and recorded failure.

The curtin config would be good as well as any user-data that was provided.
