apt signature requierements prevent updates from some repositories

Status in apt source package in Xenial:
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signatures of packages, packages from some repositories are no longer
updated.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
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.
