Title:
  apt-get update reports spurious failures

Status in APT:
  New
Status in “apt” package in Ubuntu:
  New

Bug description:
  When one entry in sources.list is incorrect, apt-get update may
  incorrectly report that other sources (which are fine) are also
  broken. This is because apt-get first looks for InRelease before
  actually downloading Release.gpg; so a single failing source will skip
  the rest of the downloads, and then later when apt-get sweeps the
  cache looking for missing Release.gpg, it concludes the other sources
  are not working either. Here is an example transcript:
