After doing a clean install of kde pclos 2012.12 updating sources list then reloading, I wind up with a corrupted database. I have rebuilt it exactly as you have posted, which then allowed me to download the approx 500 packages. As soon as it attempts to apply the packages the system crashes or freezes. When I go to reboot the system the xorg system is corrupted. Some tinkering around has got me prompted for task-X11 packages which I could not do when the system was borked again. I have duplicated this scenario at least a dozen times, trying remastered cd from other computers on dvd or external drives,
 The computer will work fine for days without updating. Installed apps,Firefox, vlc etc. all function fine with the native installs found on the 2010.12 iso or what are found on the remasters.
 None of the disks used have given me any problems on any other computer which is most puzzling. I have changed out the hard drive, memory, video card, removed cpu and reapplied thermal grease. All the temps  are as they should be. When rebuilding the database everything is looking good until the end which I am posting.

Your installation CD has become corrupted/faulty or your CD drive has lost the ability to properly read the compressed image of the LiveCD.

Thanks for the quick reply, but what baffles me is that the live cd sources are made in several other computers, when installed have functioned fine for days. Several of the installs were from live usb made from a totally independent source/machine which have all been production machines.
 I have concluded there is a problem with this new computer, but can't figure out what it may be. Forgot to mention the remastered disk has Linux 2.6.38.2-pclos1.bfs i686  Linux 2.6.38.2-pclos1.bfs i686 which is the machine I am posting from. I guess I am hoping there is an intereaction with pclos that can be tweaked before I kick this new computer out the window and hit my neighbor in the head. Hoping there is help for this almost large paperweight!

remove /var/lib/rpm then try to copy /var/lib/rpm from the livecd to the hardrive

The most likely cases of having hardware issues if you have checked the memory is usually the power supply or the motherboard.

same package twice installed

Code:

This package won't be cleanly updated, unless you leave
only one version. To leave multiple versions installed,
you may remove that warning by setting the following
option in your configuration file:

and the tip in top of the topic wont help
so try, to find out was is installed

Code:

rpm -qa | grep package_name

then

Code:

rpm -e  package-version-release --allmatches

If package required by other, so add it as follow

Code:

rpm -e  packagename package-version-release --allmatches
