Pull Request Overview
Adds a deprecation warning for Azure Linux 2.0 users and a toggle via environment variable
- Introduces a new constant
AZURELINUX2_WARNING_MESSAGEwith migration guidance - Imports
osand checksAZURE_CLI_DISABLE_AZURELINUX2_WARNINGto conditionally log the warning - Emits the warning on every CLI run when not disabled
Comments suppressed due to low confidence (1)
src/azure-cli/azure/cli/main.py:125
- The warning is logged unconditionally on every platform; add a check to detect Azure Linux 2.0 (e.g., via /etc/os-release or platform library) so it only appears for that OS.

#29628 has a sentence:
For more information: https://go.microsoft.com/fwlink/?linkid=2282203
But there is no public document for Azure Linux 2.0's EOL. https://github.com/microsoft/azurelinux doesn't mention this. There is only an internal document: https://eng.ms/docs/products/azure-linux/overview/20eol. microsoft/azurelinux#13555 was raised for this issue.

Azure Linux confirmed there will be no public announcement for Azure Linux 2.0's EOL.

The warning can also be disabled by az config set core.only_show_errors=true, but as #29628 (comment) mentioned, this will disable other warning messages too.
Introducing an environment variable AZURE_CLI_DISABLE_AZURELINUX2_WARNING will make it possible to disable only this warning message.
Adding a config option core.disable_azurelinux2_warning is also possible but a little bit too heavy and formal, an requires official documentation. AZURE_CLI_DISABLE_AZURELINUX2_WARNING is only a one-time feature and will not exist in the dev branch of Azure CLI.

Description
According to microsoft/azurelinux#13555, Azure Linux 2.0 will reach its End of Life (EOL) on July 2025.
Azure CLI 2.74.0 (release date: 2025-06-03) will be the last version that supports Azure Linux 2.0. Azure CLI 2.75.0 (release date: 2025-07-01) will not be released for Azure Linux 2.0.
Similar to #29628, this PR displays a warning message solely for Azure Linux 2.0 RPMs:
Note
This PR will not be merged into
devbranch. Instead, after 2.74.0 is released, a separate branchrelease-2.74-azurelinux2will be created and this PR will be merged into it. Then a separate release pipeline will be triggered specifically for Azure Linux 2.0.Azure Linux 2.0 support will be fully dropped by #31533
