Recommended Steps Before Installation

Before you begin, run an update on your system to ensure all packages are up-to-date to avoid any conflicts during the installation.

sudo apt update

Optionally, you can list the updates for users who require review or are curious.

sudo apt --list upgradable

Proceed to upgrade any outdated packages using the following command.

sudo apt upgrade

Install Required Packages

The following dependencies will need to be installed. Most of these packages would already be present on your system, but running the command can help ensure they’re installed.

sudo apt install dirmngr lsb-release ca-certificates software-properties-common apt-transport-https curl -y

Install PowerShell

First, you will need to import the GPG and the repository. Luckily this is straightforward, and you will always have the most up-to-date version available on your system.

Import the GPG key using the following command.

curl -fSsL https://packages.microsoft.com/keys/microsoft.asc | sudo gpg --dearmor | sudo tee /usr/share/keyrings/powershell.gpg > /dev/null

Next, import the repository with the following command that matches your Ubuntu distribution version.

First, Ubuntu 22.04 Jammy JellyFish LTS users must use the following command.

echo "deb [arch=amd64,armhf,arm64 signed-by=/usr/share/keyrings/powershell.gpg] https://packages.microsoft.com/ubuntu/22.04/prod/ jammy main" | sudo tee /etc/apt/sources.list.d/powershell.list

Secondly, Ubuntu 20.04 Focal Fossa LTS users must use the following command.

echo "deb [arch=amd64,armhf,arm64 signed-by=/usr/share/keyrings/powershell.gpg] https://packages.microsoft.com/ubuntu/20.04/prod/ focal main" | sudo tee /etc/apt/sources.list.d/powershell.list

Once done, run an APT update to reflect the new additional repository.

sudo apt update

Now you can install PowerShell using the following command.

sudo apt install powershell -y
