I also have this symptom (Xubuntu Natty Alpha 1). Updating is currently not possible with the Update Manager; apt-get update and apt-get upgrad work fine, however.
Specially mean: Apport does not report the crashes of Update Manager because - naturally - there are always outdated packages. There's already an (old) bug report. See #397519 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/674118 Title: [natty] update-manager hangs while applying updates -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
