I installed a fresh ubuntu server 20.04. Then I am unable to connect to my home internet wifi. I followed this How to enable wireless on Ubuntu Server 18.04 via CLI?, but isn't helping either. I have attached screenshot of the terminal outputs, please let me know if this is enough.

The screenshots show following outputs:

  1. Ubuntu version to confirm (Pic 1)
  2. Filename of default yaml file and its content after I changed (Pic 1)
  3. output of ip addr show. I used the wlp8s0 in the yaml file (Pic 1)
  4. output of netplan generate (Pic 2)
  5. output of netplan apply (Pic 3)
  6. error outputs when pinging (Pic 4)

What could be going wrong?

Thank you in advance.

    On your first picture you have 2 network interfaces and they all down you can read it from the output, to bring it up ip link set enp7s0 up for example – JoKeR Jun 28 at 6:31
