Since posting the above comments, I managed to get Ubuntu to boot once and, at that time, I invoked Update Manager to bring everything up to date. Since then Ubuntu boots fine but I still get this error message at the same stage of the boot process as before. But the boot process continues and Ubuntu seems to work okay. This is all very strange.
