This guide will walk you through the steps to install PowerShell on Linux Mint 21 or its older stable release of Linux Mint 20 using the official third-party APT repository. This approach ensures you can access the latest version through the command-line terminal.

PowerShell Pre-Installation Steps on Linux Mint 21 or 20

Before installing, ensuring your system is up-to-date with all existing packages is a good practice.

sudo apt update && sudo apt upgrade

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 ca-certificates software-properties-common apt-transport-https curl -y

Install PowerShell on Linux Mint 21 or 20 via APT

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

Import the GPG key using the following command.

curl -fsSL | gpg --dearmor | sudo tee /usr/share/keyrings/powershell.gpg > /dev/null

Next, import the repository. Ensure you import the correct repository that matches your Linux Mint version:

Import PowerShell for Linux Mint 21:

echo deb [arch=amd64,armhf,arm64 signed-by=/usr/share/keyrings/powershell.gpg] jammy main | sudo tee /etc/apt/sources.list.d/powershell.list

Import PowerShell for Linux Mint 20:

echo deb [arch=amd64,armhf,arm64 signed-by=/usr/share/keyrings/powershell.gpg] focal main | sudo tee /etc/apt/sources.list.d/powershell.list

Please ensure the following commands is accurately copied: Linux Mint 21 is based on Ubuntu Jammy Jellyfish, while Linux Mint 20 is based on Ubuntu Focal Fossa. If you follow guides primarily designed for Ubuntu, which incorporate the system source name into commands, be aware that using Linux Mint’s source name in these commands will not work, as the corresponding directories do not exist.

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

Activate PowerShell on Linux Mint 21 or 20
