Describe the bug
Azure CLI has dropped support for some environments:

• Ubuntu < 18.04, Debian < 10 ([Packaging] Bump embedded Python to 3.10 for deb packages #22170)
• CentOS 7, RHEL 7, SUSE ([Packaging] Drop CentOS 7 RPM package #23047)
• Python < 3.7 ([Packaging] Drop Python 3.6 support #23102)

However, in those environments, az --version still shows there are available updates:

[root@ae6b254e11cf /]# az -v
azure-cli                         2.38.0 *

core                              2.38.0 *
telemetry                          1.0.6 *

Dependencies:
msal                            1.18.0b1
azure-mgmt-resource             21.1.0b1

Python location '/usr/bin/python3.6'
Extensions directory '/root/.azure/cliextensions'

Python (Linux) 3.6.8 (default, Nov 16 2020, 16:55:22)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]

Legal docs and information: aka.ms/AzureCliLegal


You have 3 updates available. Consider updating your CLI installation with 'az upgrade'

This because Azure CLI checks the latest version from source code on GitHub repo, instead of corresponding package repo:

azure-cli/src/azure-cli-core/azure/cli/core/util.py

Lines 299 to 303 in 8357f17

	def get_latest_from_github(package_path='azure-cli'):
	try:
	import requests
	git_url = "https://raw.githubusercontent.com/Azure/azure-cli/main/src/{}/setup.py".format(package_path)
	response = requests.get(git_url, timeout=10)

To Reproduce
Lauch a CentOS 7 docker container and install Azure CLI:

docker run -it --rm centos:7

rpm --import https://packages.microsoft.com/keys/microsoft.asc

echo -e "[azure-cli]
name=Azure CLI
baseurl=https://packages.microsoft.com/yumrepos/azure-cli
enabled=1
gpgcheck=1
gpgkey=https://packages.microsoft.com/keys/microsoft.asc" | tee /etc/yum.repos.d/azure-cli.repo

yum install azure-cli

az --version

Expected behavior
az --version shouldn't show available updates in those environments.

Same problem here with SLES. There is no newer version in repository

https://packages.microsoft.com/yumrepos/azure-cli/

Last version is 2.38.0 (release date: 2022-07). Is this repository still alive? There is no information on that in the docs.

Do we have to use

az upgrade

for the future now? That would mean higher maintenance effort for companies!

I've come across this as well with RHEL7. Microsoft seem to have dropped support for 2.39.0+ from RHEL7 & CentOS7, per the install docs: https://learn.microsoft.com/en-us/cli/azure/install-azure-cli-linux?pivots=dnf&view=azure-cli-latest#overview.

Warning

Starting from Azure CLI 2.39.0 (released on 08/02/2022), no RPM packages will be released for RHEL 7 and CentOS 7. You may continue to use historical versions of Azure CLI on these systems, but there will be no further updates or bug fixes from Microsoft for those versions.

Azure CLI and the Linux Install script will continue to be developed and supported by Microsoft. Packages provided by Red Hat and CentOS repositories are maintained and supported by their respective distributions.

Just contributing for posterity's sake.
