Ubuntu installer retrieve this error while copying files during ubuntu 14.04.1 LTS installation in my laptop:

This is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment.

I have already make some checks but can't find what is causing this error:

  • Check MD5SUM (correct)
  • Try with two different USB installer, UUI and rufus.
  • Try width two different USB devices, both of them 16GB.
  • Try with a DVD
  • Try the option Check disck for defects (no errors found)
  • Memtest86+ (no errors)

What can be causing this error?

  • How far into installation? Are you connected to the internet during installation? are you able to boot to a live environment(try Ubuntu)? and have you re-downloaded the OS before each attempt? Is your laptop running on battery or wired power? – Software_Programineer Mar 24 '16 at 22:25
