I can confirm this on my machine. 10.10 32bit Fresh install. Seems to be a regression because there is no problem in a 10.04 32bit fresh install. In 10.04 update-manager asks if you would like to continue and then does so accordingly. Marking and updating description.
** Changed in: update-manager (Ubuntu) Status: Incomplete => Confirmed ** Description changed: Binary package hint: update-manager + + ------------------- + Summary: update-manager does not allow the download/installation of updated packages from "unauthenticated" sources. + ------------------- As part of my list of updates this morning I had one from a third party (Squeezebox Server from debian.slimdevices.com), which is not key- signed. When I selected OK to upgrade all of them, I got a message box "Requires installation of untrusted packages" (The action would require the installation of packages from unauthenticated sources.). The only option is 'Close' and there is no indication of what to do to authorise this! It prevented me upgrading the other packages too, until I'd unchecked the squeezeboxserver package. I guess I'll have to do it via apt-get. I'm running 10.10, fully up-to-date, and update-manager version 1:0.142.20. - --- - Architecture: i386 - DistroRelease: Ubuntu 10.10 + --- + Architecture: i386DistroRelease: Ubuntu 10.10 Package: update-manager 1:0.142.20 PackageArchitecture: all ProcEnviron: - PATH=(custom, user) - LANG=en_GB.UTF-8 - SHELL=/bin/bash - ProcVersionSignature: Ubuntu 2.6.35-24.42-generic 2.6.35.8 - Tags: maverick + PATH=(custom, user) + LANG=en_GB.UTF-8 + SHELL=/bin/bash + ProcVersionSignature: Ubuntu 2.6.35-24.42-generic 2.6.35.8Tags: maverick Uname: Linux 2.6.35-24-generic i686 UserGroups: adm admin audio cdrom dialout dip fax fuse lpadmin netdev plugdev sambashare tape vboxusers video ** Tags added: regression-release -- 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
