Comment 5 for bug 696149

Just wanted to add some information that I thought might be helpful. I have found that by using a different method of creating the boot disk (USB Boot disk created by a program executable on Microsoft XP platform named "Universal-USB-Installer-1.7.9.5.exe), the fault does not occur. Perhaps this executable program does something which the Ubuntu based USB boot drive creator does not. It was the recommended program to use on the Ubuntu 10.04 site. I downloaded it and used it to create a Ubuntu 10.04 LTS i386 USB boot drive. I mention this because I would get the lzma errors and the "failed to upgrade" errors regardless of if I was creating an Ubuntu 10.04, or a 10.10 Netbook, or desktop. I hope this information helps

P.S. - I tried clearing the cache as well as running the upgrade as the sole running process but it still gives the same error. The only time it does not give any errors is when the "Universal-USB-Installer-1.7.9.5.exe" is used to create the initial USB boot drive
