Check fedora-version

Overview

Checks the installed Fedora version against the endoflife.date API and alerts if the version is end-of-life or if newer major, minor, or patch releases are available. By default, alerts 30 days before the official EOL date. The offset is configurable.

Important Notes:

  • The --offset-eol parameter accepts negative values (e.g. -30) to alert before the EOL date, and positive values (e.g. 30 or +30) to alert after the EOL date

  • The --check-major, --check-minor, and --check-patch options each independently trigger a WARN when a newer release of the respective type is available, even if the installed version is not yet EOL

Data Collection:

  • Reads the installed Fedora version from the local system via /etc/os-release

  • Queries the endoflife.date API to determine the EOL date and available releases

  • Caches the API response in a local SQLite database to avoid repeated network requests
