@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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1558331 Title: message "The repository is insufficiently signed by key (weak digest)" is poorly worded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1558331/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
