When I run update manager, it gives me an error message saying:
if I click partial upgrade, it looks like it did during the upgrade, then says:
Not all updates can be installed
Run a partial upgrade, to install as many updates as possible.
This can be caused by:
* A previous update which didn't complete
* Problems with some of the installed software
* Unofficial software packages not provided by Ubuntu
* Normal changes of a pre-release version of Ubuntu
if I click close from the first "not all updates can be installed" dialog, it says:
Your system is up-to-date
There are no upgrades available for your system. The upgrade will now be canceled.
running the suggested line gives the following output:
Software index is broken
It is impossible to install or remove any software. Please use the package manager "Synaptic" or run "sudo apt-get install -f" in a terminal to fix this issue at first.
in Synaptic, fixing broken packages does nothing. Mark All Updates > Apply seems to work, but I'd still like to figure out why Update Manager does not?

Thanks in advance. I've looked at other threads with people having the same problem, but none of those suggestions worked.
