Hi John-91, Thank you for reaching out to Microsoft Q & A forum.  Can you able to try the steps provided by the @TP and I can be able to successfully edit and create-high-availability-vm-with-sets.sh using nano editor as instructed by @TP.  Can you follow the steps as provided by TP:

•  Please activate the sandbox, then follow the steps provided in the documentation.
• Once after done with Step-1, Before running the command in step 2, please enter the command below so that you can edit the script:

  nano create-high-availability-vm-with-sets.sh
  
  

• Use your arrow keys to navigate down to the --image UbuntuLTS line and change it to --image Ubuntu2204.
•  After you have made the change, press Ctrl-X, Y, then Enter to save and exit the editor. 

For your reference I am sharing the screenshot below:

Please note that to ensure that the accurate "learn-xxxxxxxx-" resource group name is entered in the provided command. Although the command is designed to automatically update with the correct group name, you can navigate to the Azure portal and access the Resource groups section.

Hi John,

There is an error in the exercise. Below instructions will allow you to complete it successfully.

Please navigate to Exercise - Configure a public load balancer , Activate sandbox, review permissions, sign-in, etc.

Before running the command in step 2, please enter below command so that you can edit the script:

nano create-high-availability-vm-with-sets.sh

Use your arrow keys to navigate down to the --image UbuntuLTS line and change it to --image Ubuntu2204

After you have made the change, press Ctrl-X, Y, then Enter to save and exit the editor. At this point you have "fixed" the file and can continue completing the exercise by running:

bash create-high-availability-vm-with-sets.sh <your learn-xxxx resource group name>

Please note it is critical to enter the correct "learn-xxxxxxxx-" resource group name in the above command. It should update the command to have the correct group name automatically, however, lately there has been a new bug whereby it doesn't get updated. You can find the resource group name by opening the Azure portal and clicking on Resource groups.

Thanks.
