This is probably because Ubuntu Maverick/10.10 is no longer supported (EOL).
>From Ubuntu Mailing List: This note is just to confirm that the support period for Ubuntu 10.10 (Maverick Meerkat) formally ends on April 10, 2012 and Ubuntu Security Notices no longer includes information or updated packages for Ubuntu 10.10. The supported upgrade path from Ubuntu 10.10 is via Ubuntu 11.04 (Natty Narwhal). Instructions and caveats for the upgrade may be found at https://help.ubuntu.com/community/NattyUpgrades. Note that upgrades to version 11.04 and beyond are only supported in multiple steps, via an upgrade first to 11.04, then to 11.10. Both Ubuntu 11.04 and Ubuntu 11.10 continue to be actively supported with security updates and select high-impact bug fixes. All announcements of official security updates for Ubuntu releases are sent to the ubuntu-security-announce mailing list, information about which may be found at https://lists.ubuntu.com/mailman/listinfo/ubuntu-security-announce. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/986622 Title: update manager package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/986622/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
