When I open my VS code it's currently starting a terminal using Ubuntu 18 on WSL2.
I want to update it to Ubuntu 20 and I think I have installed it correctly as when I run
lsb_release -a
I get:
Distributor ID: Ubuntu
Description: Ubuntu 20.04.5 LTS
Release: 20.04
Codename: focal
But if I try to open a terminal and select 'new distro' it only shows 18.
Due to restrictions on my work laptop I can't install a ubuntu through the microsoft store as VS code suggests. Is there a way of doing this all through the terminal?
