When 'Update Manager' starts running, it tells me that I need to do a 'Partial Upgrade', when I start doing the upgrade, it tells me "Remove package in bad state The package 'linux-headers-3.0.0-19' is in an inconsistent state and needs to be reinstalled, but no archive can be found for it. Do you want to remove this package now to continue?" When I click 'Yes' the program just closes. I have tried to go into the software center and reinstall the 'linux-headers-3.0.0-19' ubuntu software center just freezes. Right now I cannot run 'Synaptic', or remove any software. Please help!
