View Full Version : [ubuntu] downgrade to 8.04 is failing

August 14th, 2009, 02:04 AM
I had 8.10 installed and running ok. I upgraded to 9.04 but my video card prevented me from sticking with it, so I've tried to downgrade (reinstall) 8.04

I pop in the CD, reboot, and start the install process. Eventually the installation stops with a bunch of error messages which say "user not known to the authentication module."

Anyone know what's going on and how to get around it?

Hi, have you checked the cd for defects? (one of the options at the main menu of the live cd)
