[Bug 985066] Re: Ubuntu 12.04 beta2 installer fails when copying files

[Tom K]

I had this problem today as well.

- Downloaded ubuntu-12.04-desktop-i386.iso, burned it to CD.

- Booted computer from CD, chose "Install" from opening menu
 -- Installer asked for time zone, keyboard, then said "copying files"
 -- After copying files, received error: "The installer encountered an unrecoverable error...."

-  Rebooted, again chose "Install" from opening menu
   --  Same thing happened as above.

-  Re-downloaded iso file from www.ubuntu.com, burned it to CD

- Booted computer from new CD, chose "Install" as before
  --  Received same error.

- Rebooted, chose "Try" from opening menu and waited for desktop to appear
  --  Clicked on desktop "Install" icon
  --  Received same error as before

- Rebooted with Ubuntu 11.10 CD (made from 11.10 iso)
  --  Chose "Install" from opening menu
       --- Install of 11.10 worked flawlessly
            ---- Using Update Manager, performed all 11.10 updates
            ---- Using Update Manager, upgraded to 12.04 online
                  -----  Online upgrade worked as advertised
                  -----  That's how I got 12.04 running

Title:
  Ubuntu 12.04 beta2 installer fails when copying files

Status in “ubiquity” package in Ubuntu:
  Incomplete

Bug description:
  This bug was found on a generic 1.3GHz Celeron PC with 512MB RAM using
  an Ubuntu 12.04 beta CDR. It used to be my main PC - it worked OK then
  and worked with earlier releases of Ubuntu Linux.

  When installing this version of Linux, the installer comes to a halt
  with this message:-

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

  Story so far:-
  * Took 2 attempts to burn the CDR (1st disk was a cheap disk, 2nd was a Samsung disk).
  * 1st attempt to install got the above mentioned error message.
  * Rebooted and used the option to check the files on the CDR were OK. Test passed successfully.
  * Tried install - same result as the first attempt.
  * Rebooted & used the memtest86 option. Test passed successfully.
