I recently tried to install Elementary OS Juno onto my computer, and kept getting this error,
ERRNO 5 Input/Output Error during the installation.
It says along with the error popup that it could be due to a faulty CD/DVD disk/drive.
I ran the installer through a 32GB USB drive that I had used to install Kali Linux on right before trying to install Elementary OS on it, as well as Lubuntu and KDE Neon after giving up on it.
The flash drive worked fine when installing everything except Elementary OS.
I searched all over the web to find solutions, all of which I tried.
I checked the SHA-256sum, and it matched.
I tried reflashing the Bootable USB multiple times, sometimes with UNetBootin and others with Etcher, and no luck either times.
I tried changing the partitions to ext3, no luck.
I tried shrinking the EFI partition to under 256MB, no luck. Nothing seems to be working.
I know it's not the flash drive because I used it to install multiple other distros before and after trying to install Elementary OS, and those all installed with no issues whatsoever.
I did that by downloading the ISOs for Lubuntu onto the live installation of Elementary OS and then accidentally flashing it onto the flash drive I was running the live boot on, and then I installed that, then flashed KDE Neon onto the flash drive and installing that.
Any solutions would be greatly appreciated.
