Note whether azure-cli really needs an old version of Python

[MonikaReddy-MSFT]

Customer reported this issue - The documentation currently states, on the python3 requirement:

The RPM package of the Azure CLI depends on the python3 package. On your system, this may be a Python version which predates the requirement of Python 3.6.x. If this affects you, find a replacement python3 package.

Following the instructions on Fedora 33, I'm prompted to install an old version of Python, 3.6:

$ LANG=en_GB sudo dnf update azure-cli

I instead chose to ignore the python3.6 dependency and I got an older version of azure-cli instead, which states it's using Python 2.7. Is this intended?

$ sudo dnf install azure-cli -x python3.6

hi @fengzhou-msft could you pls have a look? thanks

[fengzhou-msft]

The azure-cli RPM package depends on python3, the reason that it prompts you to install python 3.6 is that on Fedora 33, the repo only has python 3.6 for python 3. You can run below commands to download the azure-cli package and install with no dependency after step 1 and 2 in Install:

$ sudo dnf download azure-cli
$ sudo rpm -ivh --nodeps azure-cli-*.rpm

Without step 1 and 2 to add the microsoft repo, you will get the old CLI version from Fedora repo.

Note that on Fedora 35 the situation is different and Fedora 33 is now past EOL.

@nemobis, we will work on dropping Python 3.6 support in #19858.
