[Bug 882860] Re: 11.04 install fails with I/O error during file copy

[Brian Murray]

The following errors generally indicate either bad media (CD / DVD) or
the drive.  Since you've said you've tried different drives I'd
recommend burning the DVD at a slower speed or trying a different blank
media.

Incidentally, is there a particular reason you are trying to install
Ubuntu 11.04?  The latest version is 11.10.

Title:
  11.04 install fails with I/O error during file copy

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  Hi all,

  I'm trying a fresh install on a new WD Caviar Green 1TB SATA3 drive
  using Ubuntu 11.04 AMD64 install cd. Ubuntu should be the only OS
  installed on the drive. Have tried 2 different ODD one internal LG
  SATA DVD and external USB DVD with same result. The mobo is AsRock
  A75M if that means something and trying to install Ubuntu in BIOS mode
  (mentioning this since this mobo is UEFI enabled too) and AHCI mode
  for the SATA controller.

  After partitioning with partman (or with already prepared partitions
  preor install) the installer fails in around 25% of process at
  "copying files" stage of the install. The error says that the file
  copy failed due to not able to write to the HDD and to check the
  CD/DVD and/or HDD for possible problems. Since I've tried two
  different DVD drives, the DVD problem is not really possible. I also
  checked the drive with fsck before install and no faults were
  reported.

  I created 4 partitions as follows and in order given below:

  /dev/sda1 /boot ext4 around 1GB (tried with smaller too)
  /dev/sda2 /        ext4 around 30GB
  /dev/sda3 swap  swap around 8GB
  /dev/sda4 /home ext4 the rest of the 1TB drive so ~ 950GB

  What I noticed after the last failed install was that the /home
  partition was left in "unknown" state when viewed with gparted. I can
  also see in the syslog/partman log that the installer has some
  problems determining the file type of this partition.

  I'll try to attach the syslog and partman log as requested by the
  installer pop-up to this bug report. Please let me know if any other
  details needed.

  Thanks,
  Igor
