Title:
  cloud-init devel net-convert crash when --debug is enabled

Status in cloud-init:
  Fix Released

Bug description:
  Since 22.2 enabling "--debug" for "cloud-init devel net-convert" will
  make cloud-init crash.

  Probably linked to 3e5938c6ae22b9f158f1404f41e3e43738cadff0 and the
  use of safe dumper.
