Was experiencing similar behaviour in Synaptic on Jaunty. Checked what would happen when using apt-get:
WARNING: The following packages cannot be authenticated! ---snip--- Authentication warning overridden. So in my case it wasn't a Synaptic bug. Checked /etc/apt/apt.conf and found "APT::Get::AllowUnauthenticated 1;". Changed it to "0" and the warning dissappeared for both apt-get and Synaptic. So not so much that "packages cannot be authenticated" as "packages will not be authenticated". Perhaps the wording of the messages could be improved? -- Packages not authenticated https://bugs.launchpad.net/bugs/33696 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
