As part of our ongoing efforts to keep the hosted actions runners updated and secure, the Ubuntu 16.04 LTS virtual environment will be removed from GitHub Actions on September 20, 2021. For workflows using
ubuntu-16.04, you will need to update your workflow files to run on
ubuntu-latest which will run on the Ubuntu 20.04 LTS environment instead.
To help make sure all affected customers are aware of this change, we will temporarily suspend workflows on Ubuntu 16.04 LTS environment for two short 'brownout' periods ahead of the final removal. Builds that are scheduled to run during the brownout periods will fail. Therefore it is recommended that you should plan to move to a supported version of Ubuntu before September 6, 2021. The brownouts are scheduled for the following dates and times:
- September 6, 2021 5:00pm UTC – 10:00pm UTC
- September 14, 2021 5:00pm UTC – 10:00pm UTC
