Found this on another forum, maybe it is a solution: Re: [Errno 5] Input/output error I was having the same problem (for 8.04), but got past it.
I got the livecd and alternate install ISOs off torrent, burned to CD and verified the livecd. I initially tried an upgrade of 7.04 using the alternate CD, something botched that (not sure what), so decided to do a fresh install and deal with getting my stuff re-installed, etc. Installing from livecd failed with the errno 5 about 3 times, consistently. I then ran diagnostics on my disks, both of which passed (although the disk I was /not/ installing to was running hot). I noticed in https://help.ubuntu.com/community/BurningIsoHowto that they recommend to burn the livecd at the slowest speed. Not sure why this would make a difference, given the first livecd I had passed verification, but I tried it (and actually burned the CD on a different CD burner on another machine). The install from that CD completed. So it may have been writing the CD slowly, or it may have been the different CD burner. Don't really know. -- [Errno 5] Input/Output Error during Live CD Installation https://bugs.launchpad.net/bugs/245794 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
