[Bug 1306977] Re: Ubuntu 14.04 amd64 beta2 install fails with "[Errno 5] Input/output error" (full disk install from USB drive)

[Phillip Susi]

No, it doesn't do any verification.  Either the .iso file is corrupt (
check it with md5sum ) or your usb stick corrupted it after it was
written.  Test the iso and if that is ok, format and recreate the usb
stick.  If the iso is corrupt, then download it again.

Title:
  Ubuntu 14.04 amd64 beta2 install fails with "[Errno 5] Input/output
  error" (full disk install from USB drive)

Status in “ubiquity” package in Ubuntu:
  Invalid

Bug description:
  I tried installing from two different USB sticks on two different
  computers, multiple times, and all hardware has been tested to work,
  so this is probably not a real disk error. The same error condition
  happens every time, towards the end of the setup process.

  The installed Ubuntu does not boot.

  I used Startup Disk Creator on Ubuntu 12.04 to write the image. The
  same image burnt to DVD installed fine, so apparently this bug only
  affects USB installs.

  This seems similar to bug #1252205.
