Last Apple update failed?

Question

The last 3 Apple updates (Migration and Sharing DVD/CD, iTunes 8.0.2 and Security Update 2008-007) are failing, an alert msg says:
"The following install step failed"
- run pre-install script for MigrationDVDCDSharingLeopard
- run preflight script for iTunes
- run pre-install script fro SecUpd2008-007.
"Contact the manufacuter..."
Must I ignore that updates?

but the verify/repair permission through Apple CD did not work, it says that there is "no valid package"...
This usually means someone has tampered with the /Library/Receipts/ folder by removing .pkg or .bom files placed there by the Apple installer application at the time the OS & associated applications were installed. These files furnish the information about correct permissions. Without them, the permissions repair cannot proceed. (It doesn't matter which application you use; they all run the same verification or repair.)
If someone has tampered with this folder it is likely that other system level folders have also been tampered with, often in a misguided attempt to remove "unneeded" files (that actually are needed) to save disk space or to somehow make the OS run faster by removing them (it doesn't). This is quite possibly the cause of your installation problems because some system files that may have been removed contain info or code necessary for the pre-installation, preflight, etc. scripts.
If this is true then you will need to reinstall the OS & any updates Software Updates lists as available for your system to reliably set things right.
BTW, how is it that your installer DVD has 10.4.6 but you are running 10.5.5? You should have a Leopard installer disk if you have installed that OS. It should install 10.5, 10.5.1, or 10.5.4, depending on its vintage. You must use this disk to follow the advice above.
