Comment 0 for bug 567899

I downloaded Ubuntu Lucid daily-live (64-bit version) and burned it onto a DVD-R (not a CD-R). Booting from the DVD gets past the Ubuntu logo with five dots, a purple background and the mouse pointer is shown, then the following message appears in a dialog box:

"The installer encountered an unrecoverable error, A desktop session will now be run so that you may investigate the problem or try installing again."

After pressing the OK button, Ubuntu shows the message "Please remove the disc and close the tray (if any) then press ENTER." and reboots after that.

The first time I had this issue was on Thursday, today I zsynced and burned the image onto another DVD, but the same problem still appears.

Comment 26 of bug #532984 seems to describe the exact same problem on a different system.
