Hi @dod38fr,

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.
