Bug#730237: apt-get update reports spurious failures (Unable to connect to ...)
Package: apt
Version: 0.9.9.1~ubuntu3
Severity: normal
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:
