i am using 10. 10 . when an upgrade listed through update-manager i tried for it but cancelled twice for want of time for downloading. But when approached for upgrade again , the answer was no upgrade possible.
Run command for listing upgrade through update-manager failed for unknown reason repeatedly. So i un- installed update-manager, and when tried for installing back , the answer was 'update-manager could not be installed. Update through synaptic also was blocked. No update or installation of any thing new was refused. On an attempt to recover update-manager i installed kdb environment , could installed back up-date manger there. Subsequently the ignome version appeared back . now the upgrade option is listed back through Update manager. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/882255 Title: No administrative actions possible (password refused) after enabling passwordless login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/882255/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
