Why cant I delete a Linux VM, showing error code: undefined?

Hello Nathan Reinbott,

Thank you for posting your question in the Microsoft Q&A forum. 

If you’re unable to delete stopped VMs in Azure despite having proper permissions, the issue may stem from lingering dependencies or resource locks. First, verify that no attached disks, network interfaces, or public IPs are preventing deletion—these must be disassociated manually if retained. Next, check Azure Resource Locks in the VM’s resource group, as read-only or delete locks can block removal. If the issue persists, try deleting the VMs via Azure CLI (az vm delete) or PowerShell (Remove-AzVM) to bypass UI glitches. Additionally, ensure no backup policies or Azure Backup vaults are retaining the VMs. If all else fails, a temporary role assignment escalation (e.g., Contributor) or support ticket may resolve hidden permission conflicts.
