Bug Description
i got the Ubuntu 20.04.2.0 LTS on ubuntu download website, got it on a usb flash drive with rufus as per advised on :
https:/
and i get that errno 5 error message
the installer encountered an error copying files to the hard disk:
something to do with disk cleaning up, or running in cooler place, or burn the cd at lower speed... but im on a flash drive ! i dont burn anything, my computer is idle and not running hot...
pc is about 4 years old, 8gb ram, was wiped and rebooted a week ago and all updated so no cobwebs in there.
this is the second time im trying... dunno what to do, im not IT savvy?!?!

It's possible you have a bad write to your USB flash drive. You should try re-writing it and/or re-downloading the ISO image.
