Как успешно установить Azure CLI

У меня возникла проблема с установкой Azure CLI. Я попробовал три метода, но все они не увенчались успехом.

Первые два из раздела «Установка Azure CLI в Windows» , я пробовал.

• установите Azure CLI с помощью PowerShell и
• Загрузите и установите последнюю версию файла Azure CLI .msi самостоятельно.
• Я попытался удалить его и переустановить, используя файл .msi.

Но во всех случаях, если я наберуaz, Я получу

az : The term 'az' is not recognized as the name of a cmdlet, function, script file, or operable program.

Затем я попытался установить Azure CLI в Linux в крайнем случае, но это тоже не удалось:

      + echo 'deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ bullseye main'
+ apt-get update
