Invalid image type error when creating webVM1 and webVM2 on public load balancer exercise using bash

Question

I'm trying to follow the instructions on the exercise "Configure a public load balancer" using the provided bash commands. However, I am encountering an error message when creating webVM1 and webVM2:

Invalid image "UbuntuLTS". Use a valid image URN, custom image name, custom image id, VHD blob URI, or pick an image from ['CentOS85Gen2', 'Debian11', 'FlatcarLinuxFreeGen2', 'OpenSuseLeap154Gen2', 'RHELRaw8LVMGen2', 'SuseSles15SP3', 'Ubuntu2204', 'Win2022Datacenter', 'Win2022AzureEditionCore', 'Win2019Datacenter', 'Win2016Datacenter', 'Win2012R2Datacenter', 'Win2012Datacenter', 'Win2008R2SP1'].

The error message suggests that the image type is invalid and lists the options for the available image types. The link to the exercise is here.

Hi Bernard Steenbergen,

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.
