I have setup a Windows Server 2012 R2 + SQL Server 2014 VM (using Image Gallery) several years ago. However, it didn't update SQL Server 2014 SP3 automatically even now. When I tried to install SP3 manually, it rolled back after restart.
I tried to enable Automated Patching feature on Azure Portal, and it displayed "Deployment succeeded" message on the Notifications, but it goes back to Disable if I revisit the setting page.
I'm not familiar with Azure and not sure where to check. How to fix this problem?
