@ Michael i've not tried your ppas, but canonical-x one, and the upgraded packages can be loaded as expected, even if the error is shown (as explained into #3 link).
On your side, to upgrade your ppas, i suppose you need to: 1) purge the actual key(s), 2) build new one(s) with sha2 to please the new apt. -- 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: After upgrading to apt 1.2.7 in Xenial, PPAs and most other third- party repositories become unusable with "The repository is insufficiently signed by key (weak digest)" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1558331/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
