Refresh the SSH host platform support list - #544
Merged
Conversation
The list dated from ~2021 and named four releases that are now past end of life upstream: CentOS 7 (June 2024), Debian 8 (2018), Ubuntu 16.04 (ESM ended April 2026), and Amazon Linux 2 (June 30, 2026).

step-ssh lifecycle support is validated on SLES 15.6, 15.7 and 16.0, openSUSE Leap 15.6 and 16.0, and openSUSE Tumbleweed.
The list claimed Ubuntu 20.04 and Debian 11, neither of which the lifecycle harness exercises (test/e2e/versions.bash starts at Ubuntu 22.04 and Debian 12), and disowned Amazon Linux 2, which the harness does test.

Describe your changes:
The host platform list on the SSH host quickstart dated from ~2021 and named four releases that have since reached end of life upstream:
The list now reads RHEL 8+ (naming the Rocky/Alma/CentOS Stream rebuilds explicitly, since "CentOS 7 or greater" no longer points anywhere), Ubuntu 22.04 LTS+, Debian 12+, and Amazon Linux 2 and 2023.
Those floors match
test/e2e/versions.bashinoslogin-server— the lifecycle E2E harness — row for row, so the page claims exactly what we exercise. That is why Amazon Linux 2 stays listed despite its upstream EOL: the harness has anamazonlinux-2row. Sunsetting it means dropping that row and this bullet together, not the bullet alone.Added a line noting that the older releases may still install and run, but are not tested or supported. This is deliberate: our packages do keep working well below the supported floor, and customers on a CentOS 7 or AL2 tail shouldn't read the tightened list as "the software will break." It draws the line at what we test rather than at what runs.
