Tip: Upgrade auf Unifi-Version 5.0.6

-> https://community.ubnt.com/t5/UniFi-Updates-Blog/UniFi-5-0-6-is-released/ba-p/1579716

-> Release Notes:
For Debian/Ubuntu users, please update your APT source (see HERE).

- unifi-beta/unifi-rapid are obsoleted. The old repo has been removed.
- use 'unifi5' in your source file, instead of 'stable' or 'unifi4'

-> In /etc/apt/sources.list
deb http://www.ubnt.com/downloads/unifi/debian stable ubiquiti

durch

deb http://www.ubnt.com/downloads/unifi/debian unifi5 ubiquiti

ersetzen und dann über 'apt-get upgrade', 'apt-get upgrade' den Unifi-Controller auf Version 5.0.6 aktualisieren. Hat bei mir problemlos funktioniert.
