I am new in Linux/k8s and trying to run az CLI on Ubuntu VM.

After following all instructions to install CLI and kubectl as following:

- Install az CLI:
    ○ AZ_REPO=$(lsb_release -cs) echo "deb [arch=amd64] 
       https://packages.microsoft.com/repos/azure-cli/ $AZ_REPO main" | sudo 
       tee /etc/apt/sources.list.d/azure-cli.list
    ○ curl -L https://packages.microsoft.com/keys/microsoft.asc | sudo apt key add -
    ○ sudo apt-get install apt-transport-https
      sudo apt-get update && sudo apt-get install azure-cli
- Install kubectl:
    ○ sudo apt-get update && sudo apt-get install -y apt-transport-https
      curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo 
      apt-key add -
      sudo touch /etc/apt/sources.list.d/kubernetes.list 
      echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee 
       -a /etc/apt/sources.list.d/kubernetes.list
      sudo apt-get update
      sudo apt-get install -y kubectl

I got the following error message if I try to run az login as root:

"Port '8400' is taken. Trying with the next one Note, we have launched a browser for you to login. For old experience with device code, use "az login --use-device-code" Running Firefox as root in a regular user's session is not supported. "

Also, if I try to run it using my non-root account, it gives me the following trace erros:

 Traceback (most recent call last):
  File "/opt/az/lib/python3.6/configparser.py", line 1138, in _unify_values
  sectiondict = self._sections[section]
KeyError: 'cloud'

During handling of the above exception, another exception occurred:

Please help.
