Comment 2 for bug 720863

Thank you for your report. This package failure looks like being caused by a corrupted file system. Please start the "Memory check" from the boot menu. If that runs successfully, please start the desktop cd. Hold right-shift key after the bios checks to get to the grub menu and run "Check disc for errors" option. If the file system corruption is serious, the safest option would be to reinstall your system. Please let us know by comment below if these checks report errors to you.
