Public bug reported: 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:
