Make /etc/resolv.conf changes permanent in WSL 2

On WSL 2, when I try to connect to a website, I get an issue:

$ ping www.google.com

ping: www.google.com: Temporary failure in name resolution

Now, to fix this, I had to add /etc/wsl.conf with this content:

[network]

generateResolvConf = true

And I need to change my /etc/resolv.conf to:

nameserver 8.8.8.8

This works fine.

However when I restart my system, when I shutdown wsl or do anything similar, /etc/resolv.conf is overwritten with the previous value.

Of course, if I change /etc/wsl.conf to the following and restart again:

[network]

generateResolvConf = false

The fix mentioned above is gone again.

So how do I make my changes to /etc/resolv.conf permanent on WSL 2?

I found this solution here

sudo rm /etc/resolv.conf

sudo bash -c 'echo "nameserver 8.8.8.8" > /etc/resolv.conf'

sudo bash -c 'echo "[network]" > /etc/wsl.conf'

sudo bash -c 'echo "generateResolvConf = false" >> /etc/wsl.conf'

sudo chattr +i /etc/resolv.conf
