{% data reusables.actions.enterprise-github-hosted-runners %}

If you require additional software packages on {% data variables.product.prodname_dotcom %}-hosted runners, you can create a job that installs the packages as part of your workflow.

To see which packages are already installed by default, see "Preinstalled software."

This guide demonstrates how to create a job that installs additional software on a {% data variables.product.prodname_dotcom %}-hosted runner.

Installing software on Ubuntu runners

The following example demonstrates how to install an apt package as part of a job.

{% raw %}

name: Build on Ubuntu
on: push

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - name: Check out repository code
      uses: actions/checkout@v2
    - name: Install jq tool
      run: |
        sudo apt-get update
        sudo apt-get install jq

{% endraw %}

{% note %}

Note: Always run sudo apt-get update before installing a package. In case the apt index is stale, this command fetches and re-indexes any available packages, which helps prevent package installation failures.

{% endnote %}

Installing software on macOS runners

The following example demonstrates how to install Brew packages and casks as part of a job.

{% raw %}

name: Build on macOS
on: push

jobs:
  build:
    runs-on: macos-latest
    steps:
    - name: Check out repository code
      uses: actions/checkout@v2
    - name: Install GitHub CLI
      run: |
        brew update
        brew install gh
    - name: Install Microsoft Edge
      run: |
        brew update
        brew install --cask microsoft-edge

{% endraw %}

Installing software on Windows runners

The following example demonstrates how to use Chocolatey to install the {% data variables.product.prodname_dotcom %} CLI as part of a job.

{% raw %}

name: Build on Windows
on: push
jobs:
  build:
    runs-on: windows-latest
    steps:
      - run: choco install gh
      - run: gh version

{% endraw %}
