Comment 79 for bug 1558331

@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.
