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:
