How to fix it ?

A: Starting with the Nios® II EDS in the Intel® Quartus® Prime Pro Edition software version 19.2 and Intel® Quartus® Prime Standard Edition software version 19.1, the Cygwin component in the Windows* version of Nios II EDS has been removed and replaced with Windows Subsystem for Linux(WSL).

So to run the NIOS II Command Shell properly, you need to follow the steps below to install.

Fix

1. Open PowerShell as Administrator

   

2. Run : Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

   

3. Restart your computer when prompted.
4. Install the Linux Distribution on your Windows 10, Please install Ubuntu 18.04 LTS for WSL from the flowing link: Ubuntu 18.04 LTS

   Note: Windows* 10 build version 16215.0 or higher is the recommended operating system version.

5. From the distro's page, select "Get"

   

6. Now that your Linux distro is installed, you must initialize your new distro instance once, before it can be used. You will be prompted to create a new user account (and its password).

8. Install additional distro packages required for Nios® II EDS using the following command:

   sudo apt install wsl

   sudo apt install dos2unix

   sudo apt install make

   

9. Once the installation is complete, the WSL is installed.
