admin user name cannot contain upper case character A-Z special characters or start with or - in Azure

Question

Hi Team,

I have configured Azure CLI in Windows. I am trying to create a VM from the command line. But it is showing me the below error.

$ az vm create -n MyVm -g MyResourceGroup --image UbuntuLTS
admin user name cannot contain upper case character A-Z, special characters \/"[]:|<>+=;,?*@#()! or start with $ or -

Hi@akhtar,

you can specify --admin-username to provide a username for the account to be created on the VM. Without that, the Azure CLI uses the username of your current shell login session. If the username you have logged into the Azure Cloud Shell or local PowerShell session contains those invalid characters, the VM create operation fails.

$ az vm create -n myvm -g MyResourceGroup --image UbuntuLTS --admin-username <user_name>

Hope it helps!
