Osquery uses basic SQL commands to leverage a relational data-model to describe a device.

not sure if that InRelease file needs to be there and is missing, or if 17.10 considers it a fatal error while 17.04 doesn't, or what

&gt; To download packages from a repository apt would download a InRelease or Release file from the $ARCHIVE_ROOT/dists/$DISTRIBUTION directory.

&gt; InRelease files are signed in-line while Release files should have an accompanying Release.gpg file.

seems like apt 1.5 used in 17.10 (also built a 1.6 and tried that) is not falling back... (since Release and Release.gpg files _are_ present in the osquery repo)

i wonder if it doesn't like that it's 403 Forbidden instead of 404 Not Found...

well look at that <https://github.com/Debian/apt/blob/38d444af2632219ab399dabadaaefaa4dcdd6ebf/apt-pkg/acquire-item.cc#L1880>
