Julian - I just tried and it seems like Post-Invoke is run when there is
a W: but not an E: - is that right?
In this snippet I've added an Apt::Update::Post-Invoke { "echo 'hello' }
Reading package lists... Done

I see <https://anonscm.debian.org/cgit/apt/apt.git/tree/apt-pkg/update.cc#n108>
which looks like it's where the function is returning from (didn't trace it
though), which would prevent the Post-Inboke hook from running.

Title:
apt signature requierements prevent updates from some repositories
Status in appstream package in Ubuntu:
Confirmed
Status in apt package in Ubuntu:
In Progress
Bug description:
Since xenial updated the requirements for the strength of PGP
signatures of packages, packages from some repositories are no longer
updated. Apt-get update reports these errors:
E: Failed to fetch http://[...]/Release No Hash entry in Release file
/var/lib/apt/lists/partial/[...] which is considered strong enough for security
purposes
E: Some index files failed to download. They have been ignored, or old ones
used instead.
While the motivation for the change is valid, the result is a
potential security problem, as the new versions of the packages that
may fix recently discovered vulnerabilities are not automatically
installed.
One less important but unfortunate effect is a scary message that is
displayed to the user, without clear explanation that the problem
needs to be addressed by the repository owner.
