brew install planck fails on Ubuntu 20 WSL2 on Windows 10

[Sean Corfield]

I successfully installed Planck on WSL1 (I think I used brew there as well). I just tried to install it on a fresh laptop running WSL2 and got this failure:

Luckily the Ubuntu / apt instructions worked fine so I am up and running.

I decided to have another go at this, given that I've updated my WSL2 environment quite a bit since September. It still fails, but differently. Here's the last section of the brew install log:

Closing due to lack of feedback/interest.
