Hi-there @Jochen! Apologies, I must have missed the notification about your comment.

The suggestion Diniz made was applicable at the time. Since then, I corrected the article which is why it may seem not necessary now.

The code in the article is written so that you can just copy the entire block of code and paste it into the command line.

The scripts in the Ubuntu folder aren't meant to be used directly. The Ubuntu icon is what calls the scripts. If nothing is happening when you click the Ubuntu icon then it might be related to your execution policy settings.

You could try the following:

1. Run `Get-ExecutionPolicy -List` in PowerShell

2. Take a screenshot or write down your current settings

3. Run `Set-ExecutionPolicy -ExecutionPolicy Unrestricted`

4. Try completing the tutorial again

5. Rerun step 3 with whichever setting you prefer

You can also read about the different execution policy settings here.
