check_os_release

This is a Nagios/Icinga plugin to check if the currently installed operating system version is outdated. It checks:

• whether the installed version is about to reach end-of-life (see --eolWarningDays, --eolCriticalDays, --eolIgnore parameters),
• or whether a newer release is available (see --releaseWarningDays, --releaseCriticalDays, --releaseIgnore parameters).

Currently only Debian and Ubuntu are supported.

Information about releases and end-of-life dates is retrieved from https://salsa.debian.org/debian/distro-info-data/ or (if --localDID is specified) from the /usr/share/distro-info directory, which is provided by the distro-info-data package.

Requirements

• Python 3
• internet access (to download the latest release data); or a local up-to-date installation of distro-info-data package (specify --localDID parameter to use this)
