Azure Docker image fails to build because python3.6 package cannot be installed

Bug report

• AirSim Version/#commit: main (current branch)
• UE/Unity version: N/A
• autopilot version: N/A
• OS Version: Windows 11

What's the issue you encountered?

While testing the Azure Docker deployment, I found that the Docker image cannot be built successfully.

The build fails when the Dockerfile attempts to install python3.6.

I reproduced the issue locally and investigated it inside the Docker base image before opening this report.

Settings

How can the issue be reproduced?

1. Clone the AirSim repository.
2. Navigate to the repository root.
3. Run:

docker build -t airsim-azure -f azure/docker/Dockerfile azure

1. The build fails while installing python3.6.

Include full error message in text form

E: Unable to locate package python3.6 E: Couldn't find any package by glob 'python3.6' E: Couldn't find any package by regex 'python3.6'

Investigation

To verify this was not a local Docker issue, I performed the following checks inside the base image (nvidia/cudagl:9.0-devel):

• apt-get update completed successfully.
• The issue was reproduced both during Docker build and by manually inspecting the base image.
• Added ppa:deadsnakes/ppa successfully.
• apt search python3.6 returned no results.
• apt-cache policy python3.6 also could not locate the package.

The build currently stops at:

RUN apt-get install -y \
    python3.6 \
    python3-pip

I haven't proposed a code change because I'd first like to confirm the preferred direction for this deployment.

If this Azure deployment is still actively maintained, I'd be happy to work on a pull request once the preferred approach is confirmed..
