Language packs downloaded OK, then crashes in last stages.
Thought I saw the text "wifi" in the little text pane and the WiFi connection was dropped just before crash.

also,
installer exited with prompt along the lines of,
OK this to exit
With no other options, what do you do?

I had a similar issue. Just bought a new MoBo, processor and ram. GA-990FXA-UD5, AMD FX8350 and 8 GB Kingston Hyper Beast DDR3 2400 Ram. After Adjusting the RAM voltage to 1.65 Volts I installed an old HDD I had from a previous build. It was used on an old Intel P4 32 Bit Dual core MoBo. Dual boot with dual drives. XP on one drive and Ubuntu 14.04 - 32 bit on the other. When booting off the Ubuntu 32 bit drive everthing was fine. Windows XP of course flipped out and crashed. (Not unexpected). Now I have a 8 Core 64 Bit processor running a 32 Bit OS. Obviously this was a little disappointing. When I tried to boot Ubuntu 14.04 - 64 Bit version, well that's when life got interesting. It would boot sometime but always lost USB and LAN ports..

Since windows was toast anyhow I wiped it an loaded Ubuntu 64 Bit on another system to get it installed. Now I have 2 identical drive, one with Ubuntu 32 Bit OS and the Other with the 64 Bit version. The 32 Bit version worked fine, but everytime I tried 64 Bit OS - no joy. I stubled another post with a similar issue and found a solution that worked. In the BIOS there is a default for IOMMU (Disabled), when I enabled the IOMMU suddenly the 64 Bit OS worked. USB 3.0, Gigabit LAN. Life is good again. Now back to the drawing board to see if I can stripe the drives since both drive are older and slower. See if I can squeeze a little more speed out of them. I hope this helps.
James.
