Same problem in 12.04 LTS: cannot install updates from an unsigned repository.
"apt-get upgrade" prompts, and lets the user decide whether to install or not: WARNING: The following packages cannot be authenticated! unsigned-package1 package2 etc. Install these packages without verification [y/N]? y Update-manager should have a similar behaviour: - Either give the option to upgrade the package(s) without verifictaion - Or upgrade the other (authenticated) packages, and tell the user that the unauthenticated package(s) should be upgraded by running "apt-get upgrade" at the command-line. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/707392 Title: Not possible to upgrade untrusted packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/707392/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
