I just got a new Acer Aspire 5 A515-56 laptop. I'm trying to install Ubuntu on it, however while installing, I keep getting an error message that says [Errno 5] Input/output error.

Error Message

After reading through similar questions, here are some things I have tried.

  • I tried installing Ubuntu 22.04 and Ubuntu 20.04 (I downloaded both iso files from the official website).
  • I tried using a different bootable drives (note that both were microSD).
  • I tried installing it the "normal way" as well as the "safe graphics" way (as my laptop does have Intel Iris Xe Graphics).
  • I tried every combination of "minimal installation"/"normal installation" and "update while installing"/"install third party software"
  • I tried using Etcher, Rufus, and Startup Disk Creator to flash the USB drives.
  • In the BIOS, I enabled F12 boot and disabled Secure Boot.
  • I have tried using different USB ports.
  • I tried disabling VMD in the BIOS.

So far everything has led to errno 5.

UPDATE: Here is the output of verifying the ISO:

thomas@computer:~$ gpg --keyid-format long --verify ~/Downloads/SHA256SUMS.gpg ~/Downloads/SHA256SUMS.txt
gpg: Signature made Thu 11 Aug 2022 07:07:33 AM EDT

And

thomas@computer:~$ sha256sum -c SHA256SUMS.txt 2>&1 | grep OK

ubuntu-22.04.1-desktop-amd64.iso: OK

Turns out my micro SD cards (or my micro SD to USB converter) were faulty. The solution was to use a USB drive. When using a new drive, the installation went flawlessly. Though this answer may not be all that instructive, I hope the troubleshooting described in the comments helps future users. Many thanks to @guiverc for the guidance!
