Installing PowerShell 7
=======================

Installing PowerShell 7 on Ubuntu
---------------------------------

1. In the first line, we are updating the local pachkages with the latest versions from the default repositories.

.. code-block:: teslapython.com

    > sudo apt-get update
    Hit:1 http://archive.ubuntu.com/ubuntu noble InRelease
    ...
    Reading package lists...Done

2. In the second line, we're installing some prerequisite packages:

.. code-block:: teslapython.com

    > sudo apt-get install -y wget apt-transport-https software-properties-common
    Reading package lists...Done
    Building dependency tree...Done
    wget is already the newest version (1.21.4-1ubuntu4.1)
    ...

3. In the third line, we are grabbing the exact version of the operating system and then using that in the fourth line:

.. code-block:: teslapython.com

    > source /etc/os-release

4. Next, we use *wget* to download the correct repository for our operating system. This is the Linux package repository for Microsoft product (packages.microsoft.com)

.. code-block:: teslapython.com

    > wget -q https://packages.microsoft.com/config/ubuntu/$VERSION_ID/packages-microsoft-prod.deb

5. We're registering packages.microsoft.com with *dpkg*, the Ubuntu package management system:

.. code-block:: teslapython.com

    > sudo dpkg -i packages-microsoft-prod.deb
    Setting up packages-microsoft-prod (1.1-ubuntu24.04) ...

6. We're deleting the key for security:

.. code-block:: teslapython.com

    > rm packages-microsoft-prod.deb

7. We're updating again to make sure we'got tyhe latest list of packages for the new repository:

.. code-block:: teslapython.com

    > sudo apt-get update
    Get:1 https://packages.microsoft.com/ubuntu/24/04/prod noble InRelease [3600 B]
    ...

8. Finally, we're installing PowerShell:

.. code-block:: teslapython.com

    > sudo apt-get install -y powershell

To start PowerShell:

.. code-block:: teslapython.com:

    > pwsh
