Can't install rust on Ubuntu 20.04 in Windows Subsystem for Linux

[owencraston]

Problem

1. went to install rust with the following command
   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
2. I chose the default install (1)
3. When I do this I get the following panic

Steps

1. I followed the Windows Subsystem for Linux Installation Guide for Windows 10
2. I installed Ubuntu from here
   • according to the description it installs Ubuntu 20.04 LTS release
3. run curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh in the WSL terminal

Possible Solution(s)

• despite the error being different I tried all the suggested solutions in this stackoverlfow issue but to no avail.
