We can see that a package is corrupted during the package download
process:

Title:
  Crashed during installation from a disk.

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  I upgraded from 11.10 to 12.04 overnight and it appeared to work in the morning. Computer began to crash randomly but would reboot. I tried updating but although updates downloaded into cache, they did not complete; I found my computer constantly downloading the same updates.
  I downloaded the  .iso and made a live DVD. My 'Home' folder is in a separate partition so I did not format that when I booted off the live disk I burned. Stopped with error message.
  I checked the list of bugs reported and there was one suggesting that an unformatted 'Home' partition could be a problem. IIRC it was listed as 'fixed' so I downloaded the  .iso again and burned a second live disk using my netbook and an external DVD drive, hoping that  .iso might have been updated.
  I have a backup of the PC's 'Home' partition so this time allowed installer on PC  to format all three partitions (root, swap and Home) using third option regarding partitioning screen.
  Same outcome.
  The netbook upgrade to 12.04 64-bit from the first live disk was successful, so I have that for day-to-day use.
