Cannot define multiple Listeners on the same IP:port

Apache2 auf localhost startet nicht mehr. Die Fehlermeldungen:
HTML: 
systemd[1]: Starting The Apache Webserver...
start_apache2[4688]: AH00526: Syntax error on line 3 of /etc/apache2/default-server.conf:
start_apache2[4688]: Cannot define multiple Listeners on the same IP:port

Ich weiß nicht, woher da plötzlich mehrere Listeners kommen sollen :confused: Der Rechner hat eine IP Adresse im LAN: 10.0.0.60

Am Anfang der /etc/apache2/default-server.conf steht schlicht folgendes:
HTML: 
ServerName localhost
ServerAdmin root@localhost
Listen 80
Listen 443
Es scheint einen Zusammenhang mit dem Upgrade von Suse 42.3 zu 15.0 zu geben.
Da meine Recherchen im Internet keinen Lösungsansatz gezeigt haben, wende ich mich mit der Bitte um Hilfe an dieses Forum.
Bin dankbar für jeden Tipp.
 
Schau doch mal wo bei deinen Konfigs das Listen definiert wird:
Code: 
grep -R -B4 -A4 -ni Listen /etc/apache2/

Du definierst die Listen Directive für jeden Port zweimal. Einmal in /etc/apache2/listen.conf und einmal in der default-server.conf. Eine von beiden ist überflüssig. Ich würde sagen, die müssen aus der default-server.conf raus. Bei Debian sieht die Dateistruktur in /etc/apache2 etwas anders aus, daher kann ich (als Debian-User) nicht mit Sicherheit sagen, wie es bei OpenSUSE aussehen müßte.

Vielen Dank, das hat mein Problem gelöst.
Habe folgende zwei Directiven aus /etc/apache2/default-server.conf entfernt:
Code: 
Listen 80
Listen 443
Und der Server startet wieder.
 
Das hat dir Apache auch so gesagt, wo es zu viel drin ist.
Manche globale Direktive kann man auch nicht irgendwo einfach schnell rein schreiben ohne sich über die restliche Konfiguration informiert zu haben.
Changelogs des Apache lesen ist auch nützlich, wenn da sich mal was bei den Distributionsupgrades geändert hat.
Nimm dir doch mehr Zeit.
