FEniCSx on Google Colab

installation
1

Has anyone been able to successfully launch FEniCSx on the Google Colab platform? I stumbled across an example by github/bilgin-kocak available at the following link but it does not seem to run anymore.

Specifically in the Google Colab (Python3 on Ubuntu 18.04.3), I’ve tried running the FEniCSx Ubuntu PPA installations:

add-apt-repository ppa:fenics-packages/fenics
apt update
apt install fenicsx

This will return the following Error, shown in the last line of the following image:
E: Unable to locate package fenicsx

.

Does anyone know what I may be missing in order to install fenicsx?

However, there are workarounds for this at:

Thank you for clarifying that! It seems that the code from the FEM on Colab link is working now - I appreciate the help.
