I have my own local repo and am getting this error for it whenever I try to do apt-get update. I even recently updated the key I use to sign it to RSA/RSA 2048/2048 and also add the two lines in ~/.gnupg/gpg.conf:
cert-digest-algo SHA256 digest-algo SHA256 as recommended at http://askubuntu.com/a/776599/170127. However I still keep getting this error. Please advise as to what I have to do to stop getting this error. -- 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.
