Replace Ubuntu 16.04 LTS in layer definitions (end of standard support) #1214

Open dpward opened 2 years ago

dpward commented 2 years ago

Ubuntu 16.04 LTS reached the end of standard support in April 2021. Updates are only provided through Extended Security Maintenance (ESM) which must be purchased from Canonical[^1]. The latest publicly-available version of Ubuntu 16.04 LTS is affected by 343 CVEs.

The layer definitions for Ubuntu 16.04 LTS should be changed to target a newer release. Base images are currently available for Ubuntu 18.04 LTS and 20.04 LTS, which remain under standard support.

[^1]: ESM is free for personal use on up to 3 systems. For use on GCP or other public clouds, Ubuntu Pro is a paid image that includes ESM.
