actions/setup-python@v4 is unable to install python in the ubuntu example because of wrong user permissions on /opt/hostedtoolcache #2303
Description
When using the ubuntu example and running a job that uses actions/setup-python@v4 like this:
jobs:
isort:
runs-on: [self-hosted, ubuntu20.04-self]
steps:
- uses: actions/checkout@v3
- uses: actions/setup-python@v4
with:
python-version: 3.8
- uses: isort/isort-action@master
The following error is thrown (this is the output in the githbub action)
> Run actions/setup-python@v4
Version 3.8 was not found in the local cache
Version 3.8 is available for downloading
Download from "https://github.com/actions/python-versions/releases/download/3.8.13-2717995909/python-3.8.13-linux-20.04-x64.tar.gz"

Check if Python hostedtoolcache folder exist...
Creating Python hostedtoolcache folder...
Error: mkdir: cannot create directory ‘/opt/hostedtoolcache/Python’
Error: : Permission denied
Error: The process '/usr/bin/bash' failed with exit code 1
It seems like this happens because the example user_data.sh script uses the upercase variable $USER_NAME while the install_runners.sh script that sets the permissions on /opt/hostedtoolcache uses $user_name.
I created a PR that fixes this and can sucefully run the above job on our setup:
