Re: [Trisquel-users] Installing Trisquel

The installer should offer you an option to check its integrity. An I/O error  
suggests there is a problem with the install media.

The fix is to redo the install media, if you're burning a CD, use a slow  
speed. I guess it could also be a problem with the drive but that's less  
common.
