As a sidenote, talkplugin is still needed for Firefox users (I don't know why, Firefox has fully functional WebRTC now, but there you go). Last published plugin package is of April 2015.
In the long term, it would make sense to modify upstream apt to clearly distinguish between the problems that are under the user's control and those under the repo owner's control, and report it e.g. via the return code or the error message prefix. Then GUI tools could give the user better advice than the misleading "Check your internet connection" message. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1562733 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xenial updated the requirements for the strength of PGP signatures of packages, packages from some repositories are no longer updated.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.
