Today I downloaded Ubuntu for my laptop. It runs great from a bootable USB, but when I tried to install it, I got the following error message:
The installer encountered an error copying files to the hard disk:
[Errno 5] Input/output error
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 often
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 tried everything to install it on my laptop including redownloading the Ubuntu ISO image, but nothing worked.
