[Bug 1448466] Re: Installer exits because of IO error

[Phillip Susi]

Then it is being read wrong in the target machine.  Another thing you
might try is running the memtest option from the boot menu and let it go
for at least 15 minutes and see if it finds any errors.

Title:
  Installer exits because of IO error

Status in ubiquity package in Ubuntu:
  Invalid

Bug description:
  I'm installing Ubuntu Gnome 15.04 using a live DVD. I have attemped to
  install it using two different usb sticks as well, with similar
  results. I have also re-downloaded the ISO, in case it was damaged
  somehow.

  The installer gets to roughly the part where it starts to actually
  install the OS (after asking for username, password, etc.), then the
  popup appears, saying that there's an IO error.
