I'm running Lucid and whenever I open Update Manager, it says I should run a partial upgrade. I think this may have happened when I was trying to update and my computer shut off. So I click Partial Upgrade and while it's calculating the changes, it gives me an error. It says:
Could not calculate upgrade An unresolvable problem occurred while calculating the upgrade. The package update-manager-kde is marked for removal but it is in the removal blacklist. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu This is most likely a transient problem, please try again later.
This is extremely frustrating, and every time I try to upgrade, this happens. I might just try
sudo apt-get install -f to fix it, but that's all I can think of to fix this problem.
sudo apt-get install -f did not work.
