@Mahmoud F.Elshazly (elshazly5) this bug is about the wording of a message, not about specific repositories.
However, only one of the repositories is an Ubuntu repo, and that one is for trusty not xenial, so it is not appropriate to be using it at all. For the non-ubuntu repos you will have to take up the problem with them, or ask in a more appropriate place. -- 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/1558331 Title: message "The repository is insufficiently signed by key (weak digest)" is poorly worded Status in apt package in Ubuntu: Fix Released Bug description: The title pretty much says it all.
