Error while accessing Update Settings in my VM

Question

I'm trying to set up automatic VM guest patching, but whenever I go to the "Update Settings" on my VM, I keep getting "Error occured while fetching the data for the selected machine(s), please try again." - has anyone else had this issue?

I have tried through the az cli too, but I get a different error message :

az vm update --resource-group "my-resource-group" --name "my-vm" --set osProfile.windowsConfiguration.enableAutomaticUpdates=true osProfile.windowsConfiguration.patchSettings.patchMode=AutomaticByPlatform

Couldn't find 'windowsConfiguration' in 'osProfile'. 'osProfile' does not support further indexing.

@Anonymous Welcome to Microsoft Q&A, thank you for posting your here!!

Could you please try to follow below process to enable automatic VM guest patching

• Validate the extension isn't enabled You shouldn't see a patch setting section.

  az vm get-instance-view --resource-group myResourceGroup --name myVM  
  

• Enable the Preview for the subscription

    az feature register --namespace Microsoft.Compute --name InGuestAutoPatchVMPreview  
    az provider register -n Microsoft.Compute  
  

  It can take up to 15 minutes, but you can check the status with az feature show --namespace Microsoft.Compute --name InGuestAutoPatchVMPreview
• Update the existing VM to have it

     az vm update --resource-group myResourceGroup --name myVM --set  
     osProfile.windowsConfiguration.enableAutomaticUpdates=true  
     osProfile.windowsConfiguration.patchSettings.patchMode=AutomaticByPlatform  
  

• Now validate you got it...

    az vm get-instance-view --resource-group myResourceGroup --name myVM  
  

  You should see: "patchSettings": {
  "patchMode": "AutomaticByPlatform"
  },

Hope this helps!

@Anonymous Thanks for sharing the update.

Please check on the following and let me know the results in the comments. If you are still seeing this issue after confirming on the following, I will further investigate on it.

• Automatic VM guest patching is supported only on VMs created from images with the exact combination of publisher, offer and sku from the below supported OS images list. Custom images or any other publisher, offer, sku combinations are not supported.
  Can you please check if your VM is supported.
  https://learn.microsoft.com/en-us/azure/virtual-machines/automatic-vm-guest-patching#supported-os-images
• There are also certain requirements for enabling automatic VM guest patching. Please ensure that you meet all of these:
  https://learn.microsoft.com/en-us/azure/virtual-machines/automatic-vm-guest-patching#requirements-for-enabling-automatic-vm-guest-patching
• Lastly, but most importantly, to enable automatic VM guest patching on a Windows VM, ensure that the property osProfile.windowsConfiguration.enableAutomaticUpdates is set to true in the VM template definition. This property can only be set when creating the VM.

Hello @Anonymous

I'm facing issue to change Machine patching orchestration from Manual to Customer Managed schedule.

getting below error.

Saving update settings failed for 1 out of 1 machine(s) Failed for the following : myvm : The patchMode 'AutomaticByPlatform' is invalid. For patchMode 'AutomaticByPlatform', the property 'enableAutomaticUpdates' must be set to true. Also, this operation cannot be performed when extension operations are disallowed. To allow, please ensure VM Agent is installed on the VM and the osProfile.allowExtensionOperations property is true.

Can you please help.

I tried to change through script and tried to change os profile through azure PowerShell but didn't work as well as tried to change registry setting from machine but wasn't get success. if you can help me.
