Das letzte Update für Debian 9 Stretch ist erschienen.
After this point release, Debian's Security and Release Teams will no longer be producing updates for Debian 9. Users wishing to continue to receive security support should upgrade to Debian 10, or see https://wiki.debian.org/LTS for details about the subset of architectures and packages covered by the Long Term Support project.
Wird also Zeit, mal langsam drüber nachzudenken auf Debian 10 Buster zu upgraden.
