I'm using wsl 2 currently but it seems I can't run Ubuntu with it anymore. So I want to downgrade my wsl from 2 to 1

The way you address this makes it a windows question: maintaining WSL is done from Windows tools. if you want to answer the reason for why you can not run Ubuntu find error(s) notice(s) and we can have a look at them In theory your problem could be hardware related and installing wsl1 might not be a fix. — Rinzwind, Apr 28, 2021 at 6:52

How to set your wsl instance version

First list your distribution

C:\WINDOWS\system32>wsl --list
Windows Subsystem for Linux Distributions:
Ubuntu-18.04 (Default)

And then set it to version 1

C:\Users\priv>wsl --set-version Ubuntu-18.04 1

But if your problem is your rootfs, you might need to reset your instance like matigo's answer suggested.

I do not believe you can downgrade, but you can completely reset WSL2 with a couple of commands:

Alternatively, depending on which version of Windows you're using:

Open "Add/Remove Programs"
Find "Ubuntu" and access the advanced options
Choose from:
- repair ⇢ attempts to fix any broken configuration files
- reset ⇢ returns the installation to default (same as the process above)
- terminate ⇢ kill the VM, darn the consequences
- uninstall ⇢ remove WSL2 from the system
