fastai/fastai:latest, apt-get update, GitHub PPA missing Release file for Ubuntu Jammy

[LTeder]

Hello!

I'm using the Docker container fastai:fastai/latest for a project I'm working on. I need to install the onnxruntime-gpu and opencv-python-headless packages using pip. I thought I needed some extra dependencies from apt, so I attempted to update the package list before installing, but this threw an error.

Dockerfile:

FROM fastai/fastai:latest

RUN apt-get update

ENTRYPOINT ["/bin/bash", "-c"]

This fails as so:

Terminal Output

The build fails because the GitHub CLI PPA has no release file for Ubuntu 22.04 LTS ‘Jammy Jellyfish.’ In the Dockerfile, I remove this repository before pulling updates, which fixes the build error.

Dockerfile:

FROM fastai/fastai:latest

RUN add-apt-repository -r https://cli.github.com/packages
RUN apt-get update

ENTRYPOINT ["/bin/bash", "-c"]

I had one of those moments where the original problem was fixed while I worked on this nested problem. I thought I should bring it to your attention nonetheless.

I'd also like to say: I've been using fastai for over a year now. Many thanks for developing such a great module along with fastbook and nbdev. They've all been great assets as I've learned about neural networks and modern software development.
