cant run command: sudo apt-get python3.6-dev

Hi there,

I cannot deploy due to needing some c compiler files that are available in python3.6-dev
You cannot pip install them so you must apt-get.
The Actions deployment complains about stability of the cli etc.
What is the correct way to get this installed so I can take care of the dependencies that keep breaking in my requirements.txt

My yaml is as follows:
.github/workflows/master-appName(production).yml

    name: Azure App Service - appName(Production), Build and deploy Python app
    
    on:
      push:
        branches:
          - master
    
    jobs:
      build-and-deploy:
        runs-on: ubuntu-latest
    
        steps:
        # checkout the repo
        - name: 'Checkout Github Action'
          uses: actions/checkout@master
    
    
        - name: Set up Python version
          uses: actions/setup-python@v1
          with:
            python-version: '3.6'
    
        - name: apt get python 3.6-dev and shap
          run: |
            sudo apt-get install python3.6-dev
            pip install shap
    
        - name: Build using AppService-Build
          uses: azure/appservice-build@v2
          with:
            platform: python
            platform-version: '3.6'
