Install Azure CLI on Debian 13 - missing trixie directory

[Trikenstein]

Describe the bug

As of 2025-09-05, az CLI version 2.77.0. The documentation
Install the Azure CLI on Linux, Option 2: Step-by-step installation instructions has a slight mistake which will install a corrupted az CLI.

# Copy from doc

AZ_DIST=$(lsb_release -cs)
echo "Types: deb
URIs: https://packages.microsoft.com/repos/azure-cli/
Suites: ${AZ_DIST}
Components: main
Architectures: $(dpkg --print-architecture)
Signed-by: /etc/apt/keyrings/microsoft.gpg" | sudo tee /etc/apt/sources.list.d/azure-cli.sources

The reason is because lsb_release -cs gives trixie on Debian13. And https://packages.microsoft.com/repos/azure-cli/dists/ doesn't have any repo named trixie

WORKAROUND

Hardcode Suites: bookworm which is exactly what the InstallAzureCLIDeb does.

PROPOSED SOLUTION

• Elegant: create trixie directory in https://packages.microsoft.com/repos/azure-cli/dists/. Current Azure documentation remains correct
• Sloppy: Fix the Azure doc with the hardcoded Suites: bookworm

Related command

Some commands like az login output some warning & error but still functional. However az monitor will squarely FAIL

az monitor metrics alert list --resource-group myResourceGrp --query '[].name' -o tsv

Hi @Trikenstein,

This is not the official Azure CLI published by Microsoft.

How to tell if the installed Azure CLI is unofficial:

• Unofficial Azure CLI deb packages are distributed by Linux repositories #19640 (comment)
• Unofficial Azure CLI deb packages are distributed by Linux repositories #19640 (comment)

Please follow https://learn.microsoft.com/en-us/cli/azure/install-azure-cli-linux to install Microsoft official Azure CLI.

If you feel that further discussion is needed, please add a comment with the text /clibot unresolve to reopen the issue.
