I do not know, but these problems with apt-get are almost making me go
back to 14.04

Title:
  apt signature requierements prevent updates from some repositories

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  signatures of packages, packages from some repositories are no longer
  updated.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.
