"could not calculate the upgrade" from 7.04 to 7.10

/var/log/dist-upgrade/term.log existed, but was empty.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at [WWW] https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in update-manager.

After my upgrade to '7.10' failed via the Package Manager, I instead just updated the current release (equivalent of 'apt-get update && apt-get upgrade'). The only package that was unable to be resolved/upgraded was 'nfs-common'. I did an 'apt-cache show nfs-common' and am attaching the output. This output includes the two packages: one being upgraded from (1:1.0.9-2ubuntu1) and one being upgraded to (1:1.0.12-4).
