No (easy) networking after upgrade to Xubuntu 20.04.1 LTS

  • 772

After taking the option to upgrade to Xubuntu 20.04.1 LTS I no longer have any networking capability.

E.g. Output of ping www.Google.com :

ping: www.Google.com: Name or service unknown

Output of ping 192.168.0.1 (my network router):

ping: connect: Network is unreachable

Result of wireless-info script: https://paste.ubuntu.com/p/xQzTjkBZ6t/

At first I thought this was "just a Wi-Fi issue", so I tried tethering, and I am now using a cat 5 cable to my router, with the same result.

Following some stfw, I can manually bring up my Ethernet interface, after each boot with:

sudo ip link set dev enp6s0 down
sudo dhclient enp6s0

Something more permanent (and something that will get WiFi working) would be nice though!

Any ideas please?

    In your wireless script, we see:

    NetworkManager is not installed (package "network-manager").

    Using the connected ethernet, open a terminal and do:

    sudo apt update
sudo apt install network-manager

    Reboot. Clicking the Network Manager icon at the top right should now permit you to connect easily with wireless or ethernet.
