"""
Post-release script to publish artifacts created from Azure Pipelines.
This currently includes:
* Moving snaps from the beta channel to the stable channel
* Publishing the Windows installer in a GitHub release
Setup:
- Create a github personal access token
- https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token#creating-a-token
- You'll need repo scope
- Save the token to somewhere like ~/.ssh/githubpat.txt
- Install the snapcraft command line tool and log in to a privileged account.
- https://snapcraft.io/docs/installing-snapcraft
- Use the command `snapcraft login` to log in.
Run:
python tools/finish_release.py ~/.ssh/githubpat.txt
Testing:
This script can be safely run between releases. When this is done, the script
should execute successfully until the final step when it tries to set draft
equal to false on the GitHub release. This step should fail because a published
release with that name already exists.
