CLI 2.0 instructions don't work

[ambakshi]

I tried 'az extensions add --name dns', and got this (on Ubuntu 16.04/xenial)
$ az extension add --name dns
Linux distro check: Mismatch distribution name in /etc/apt/sources.list.d/azure-cli.list file
Linux distro check: If command fails, install the appropriate package for your distribution or change the above file accordingly.
Linux distro check: /etc/apt/sources.list.d/azure-cli.list has 'is', current distro is 'xenial'
An error occurred. Pip failed with status code 1. Use --debug for more information.

There was a comment in the list file that it didn't parse. I fixed that, now it doesn't recognize wheezy. Changed the .list to reference xenial, just to get past this and it still fails. Adding --debug I get:

I managed to get it working by doing the following steps manually:

mkdir -p ~/.azure/cliextensions/dns
cd ~/.azure/cliextensions/dns
wget https://dnscliextension.blob.core.windows.net/cliextensions/dns-0.0.2-py2.py3-none-any.whl
unzip dns-0.0.2-py2.py3-none-any.whl

@ambakshi Thanks for the feedback. We are actively investigating and will get back to you soon.

@ambakshi Change /etc/apt/sources.list.d/azure-cli.list to match your distro (so xenial) then run apt-get update. This will pull down the xenial version of the CLI. Then, the extension add should work.
See my comment at Azure/azure-cli-extensions#65 (comment)

That fixed it, thank you!
