ubuntu-security-status --unavailable

Wieso eigentlich das Repo und nicht die offizielle Paketquelle von Ubuntu?

Aus der offiziellen Installationsanweisung https://www.qgis.org/de/site/forusers/alldownloads.html:

Die normalen Debian und Ubuntu-Softwarerepositorien enthalten meist nur alte QGIS-Versionen.Um neuere Versionen zu installieren, müssen alternative Softwarerpositorien durch Anhängen von deb-Zeilen an die Datei /etc/apt/sources.list eingebunden werden.
