When I try to use update-manager I get this message:
An unresolvable problem occurred while initializing the package information.
Please report this bug against the 'update-manager' package and include the following error message:
'E:Unable to parse package file /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_lucid_universe_ binary-i386_Packages (1), E:The package lists or status file could not be parsed or opened.'
This came after my computer shut down in the middle updating to 10.04.
