I was experiencing this error message appearing after the plymouth boot screen and before the login screen. Using 10.10 (maverick).
I enabled maverick-proposed repository by System/Administration/Update Manager/Setting.../Updates/Proposed updates (maverick-proposed), then using Update Manager (had to select 6 updates and deselect all others). On reboot the error message has disappeared - success! Thanks.
