How do I reset the password in WSL2 in Ubuntu 20.4LTS?

[tangara]

I was following a video that said :

Change to the root user after logging in:

sudo su - # I found out we can do sudo -s

So, here's where I am stuck:

tangara@DESKTOP-SB41UI7:~$ sudo -s
[sudo] password for tangara:

Now, it seems the root user is me tangara.

But, I have forgotten my password.

How do I reset it ?

I am on Windows 10 system.

Hope someone can help me out on this.

Tks a million

I don't know anything about WSL2.
Setting any root password is not the Ubuntu way. In general, Ubuntu's root account doesn't have any password.
https://help.ubuntu.com/community/RootSudo
The passwd command can set the password for any user, however.

But WSL2 is from Microsoft and they can do whatever they want, as we've learned over the decades.

There is only 1 userid named "root". Your userid is ****not**** root on ubuntu. It may be able to elevate privilege for a short time using sudo, but that isn't the same as "being root."

Be aware that if you are introduced to Windows 11, from what I read. Microsoft forces secure boot on always.
Unlike today where it is optional.
The conclusion I draw is that Windows 11 and Ubuntu cannot coexist in dual-boot mode, other than using the native Ubuntu offered by WSL2 which is not dual-boot. I have bookmarked that little nugget of information.

Ouch. Happy to be using virtual machines for Windows instead.

Ubuntu works fine with Secure Boot. The only caveat is that if you're using kernel modules that aren't signed by Canonical (VirtualBox and the Nvidia driver being prime candidates) then you need to sign them yourself and tell your UEFI to trust your signature.

To close on this point about secure boot I searched further and found this thread which indicates that I can use ReFIND as signed boot loader which is ideal for my own usage (I use ReFIND today in dual boot).
