I undid-the duplicate; the other bug was about upgrading beyond sha-1 signatures and 1024 bit DH keys, and that's been done.
After I added the new key I have trouble fetching from ddebs using 14.04 LTS: W: Failed to fetch http://ddebs.ubuntu.com/dists/trusty/main/binary- amd64/Packages Hash Sum mismatch W: Failed to fetch http://ddebs.ubuntu.com/dists/trusty/universe/binary- amd64/Packages Hash Sum mismatch W: Failed to fetch http://ddebs.ubuntu.com/dists/trusty/multiverse /binary-amd64/Packages Hash Sum mismatch W: Failed to fetch http://ddebs.ubuntu.com/dists/trusty/main/binary-i386/Packages Hash Sum mismatch W: Failed to fetch http://ddebs.ubuntu.com/dists/trusty/universe/binary-i386/Packages Hash Sum mismatch W: Failed to fetch http://ddebs.ubuntu.com/dists/trusty/multiverse/binary-i386/Packages Hash Sum mismatch Thanks ** This bug is no longer a duplicate of bug 1558823 ddebs.ubuntu.com gpg signatures use sha-1 -- 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/1561033 Title: Can't add ddebs.ubuntu.com and update Status in apt package in Ubuntu: Confirmed Bug description: Tried following adding ddeb procedure here: https://wiki.ubuntu.com/DebuggingProgramCrash Err:7 http://ddebs.ubuntu.com xenial/main amd64 Packages Writing more data than expected (3453598 > 3453008) Get:9 http://ddebs.ubuntu.com xenial/universe amd64 Packages [3,165 kB] Err:9 http://ddebs.ubuntu.com xenial/universe amd64 Packages Writing more data than expected (9628933 > 9600688) Fetched 80.9 kB in 9s (8,683 B/s) Reading package lists...
