@RedSingularity, apturl-kde is unrelated to the error, it is not even installed on the system. It appears in the logs because the resolver checks if it can be installed as an alternative to apturl which can't be upgraded.
@Phil, it seems that the problem is with libnspr4 which has been reintroduced in natty (libnspr4-0d as been renamed) and is holding back essential packages. I haven't found the reason yet. A possible candidate could have been libreoffice for maverick but all the packages have been uninstalled. Could you double check though. I'll continue to investigate. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/773631 Title: Maverick->Natty upgrade fails: "Could not calculate the upgrade" -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
