I am working in Azure Student and trying have created a VM. I am trying to generate ssh keys and keep getting this error: {"status":"Failed","error":{"code":"DeploymentFailed","target":"/subscriptions/815b37e5-b202-482e-90dd-af9ffbf4c6dd/resourceGroups/NewLearner/providers/Microsoft.Resources/deployments/vm_deploy_56edZxBG1RmfMvRzTXd04UIq6DwQKxxS","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-deployment-operations for usage details.","details":[{"code":"PropertyChangeNotAllowed","target":"imageReference","message":"Changing property 'imageReference' is not allowed."}]}}

I have not changed the Image when setting up my Resource Group or VM. I used the default. I have tried to fix this situation myself but can't get it to work. Can someone help? Thanks!

Hi Deborah Berube,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here. Based on your query, I understand that you are facing an issue and receiving the error: {"status":"Failed","error":{"code":"DeploymentFailed"}}.

To address the issue, could you please check if there are any compatibility issues with the existing VM? Also, ensure that you are not using the same names as the existing ones on other VMs. Additionally, double-check the resource group permissions
and also refer this documentation policy and limits about the azure student subscription
Azure for Students
Azure subscription and service limits, quotas, and constraints

And also confirm A few more things Could you please specify which VM you are using and its version? Was SSH key authentication previously used, or have you configured username and password authentication? Lastly, which region are you are deployed this resource?

Providing this information quickly will help resolve the issue

Please let me know if you need any other information will help as you needed.!

Hi Deborah Berube,
You are currently using a username and password for authentication. Could you please confirm the following?

Are you using Windows or Linux?

Which region are you deploying to?

Are you using an ARM template, or Azure portal UI?

To perform this task generating ssh keys, could you please let me know.

I'm using Windows. But we are supposed to set up a Linex VM. The region is West US. I'm not sure what an ARM template is. Sorry. It's an Azure Student Portal (Azure for Students Subscription).

I don't know if my last comment went through. I am in a Windows environment trying to set up a Linex VM. The region is West US. Not sure what an ARM template is (sorry) but it's an Azure Student Subscription. Azure for Students.

If you are using an ARM template to deploy the VM, verify that the imageReference property is not being modified in subsequent deployments because it must remain consistent with the initial deployment.

If the VM is not yet in production and you can afford to recreate it, consider deleting the existing VM and deploying a new one with the correct imageReference from the start.

Delete the existing VM.

Make sure that the imageReference in your deployment template or configuration is set correctly.

Redeploy the VM.

If the issue is related to generating SSH keys, you can use Azure CLI or PowerShell to generate the keys separately and then associate them with your VM.

az sshkey create --name "mySSHKey" --resource-group "NewLearner"

New-AzSshKey -ResourceGroupName "NewLearner" -Name "mySSHKey"

I am taking an Azure class through a community college. The Azure account is through a student subscription. I have created and deleted numerous VMs and still getting the same error. I am new to all of this, so forgive me, I don't know much. We are only allowed to change a few areas when trying to create a VM, almost everything is left in default mode. I don't know if the "imageReference" is correct or not because it is in default mode. Obviously, it's not because I keep getting an error. Let me try some of your helpful advice. I will post again shortly.

Thank You!

See....it deploys but then crashes.

SSH key files '/home/dmberube/.ssh/id_rsa' and '/home/dmberube/.ssh/id_rsa.pub' have been generated under ~/.ssh to allow SSH access to the VM. If using machines without permanent storage, back up your keys to a safe location.
