Ich versuche, meinen Computer mit Ubuntu 20.04.1 an einen Ethernet-Switch anzuschließen. Wenn ich das Kabel anschließe, wird unter Einstellungen->Netzwerk „Verbunden – 100 Mbit/s“ angezeigt. Dort ifconifgund anderswo kann ich sehen, dass die Ethernet-Schnittstelle eno1nun eine IP-Adresse, eine Standardroute und eine DNS-Adresse hat, die über DHCP bezogen werden. Das Browsen ist jedoch weiterhin nicht möglich. Wenn ich denselben Computer über ein Linux Live USB (nicht Ubuntu) starte, ist er über dasselbe Ethernet-Kabel problemlos mit demselben Gerät verbunden. Ich habe auch versucht, eine statische IP-Adresse zuzuweisen, ohne Erfolg. Ich kann nicht herausfinden, was fehlt. Ich habe die Protokolldetails mithilfe von gesammelt journalctlund sie sind unten angehängt. Eine Sache scheint in den Protokollen zu fehlen: CONNECTED_GLOBAL, was ich bei anderen Verbindungen gesehen habe. Ich bin jedoch nicht sicher, ob es irgendeinen Effekt hat. Ich bin für jede Hilfe zur Lösung dieses Problems sehr dankbar.
Hier sind die Protokolldetails. Aus den Protokollen können Sie auch ersehen, dass keine Verbindung zu daisy.ubuntu.com hergestellt werden kann.
