This is affecting me trying to update the debian-multimedia package in Ubuntu. Running 'make dist" in the debian-multimedia package worked in December 2018. Now it fails with:
apt.cache.FetchFailedException: W:GPG error: http://ftp.debian.org/debian testing InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7638D0442B90D010 NO_PUBKEY 04EE7237B7D453EC, E:The repository 'http://ftp.debian.org/debian testing InRelease' is not signed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1814536 Title: out of date: 2017.7 -> 2018.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-archive-keyring/+bug/1814536/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
