Hacking Trouble setting up Ubuntu

[DahCoh]

Hello! I've been trying to set up ubuntu on my switch but keep getting the same error that says "Failed to mount rootfs". I've tried doing the installation process from scratch multiple times with different versions of ubuntu but no luck. Below is a log that was in a note file on the root of the fat32 partition. I think it says whats wrong but I don't really understand it. Does anyone know what it means? Thanks in advance.

I found out what was wrong! Just in case someone with the same problem runs into this thread in the future: i had a bad sd card. i ran h2testw on it and it was defective. bye
