[BUG] RunPowerShellScript execution hangs while deprovisioning Linux VM with waagent

RunPowerShellScript hangs while executing ‘sudo waagent -deprovision+user -force’

I want to be able to deprovision a VM from Azure Runbook. I’m using PowerShell as follows:

$restUri = 'https://management.azure.com/subscriptions/'+ $azContext.Subscription.Id+'/resourceGroups/'+$resourceGroupName+ `
    '/providers/Microsoft.Compute/virtualMachines/'+$VMName+'/runCommand?api-version=2017-03-30'
$body = @{
  'commandId' = 'RunShellScript'
  'script' = @('sudo waagent -deprovision+user -force')
}
$response = Invoke-webrequest -Uri $restUri -Method Post -Headers $authHeader -Body $($body | ConvertTo-Json)

$asyncstatus = $($response.headers.'Azure-AsyncOperation')
$status = "InProgress"
While($status -eq "InProgress")`
{
  Write-Output "Status: $status"
  $response = invoke-webrequest -uri $asyncstatus -Headers $authHeader
  $status = $($response.Content | ConvertFrom-Json).status -eq "InProgress"
  sleep 5
}

Write-Output $($response.Content | ConvertFrom-Json).properties.output.message

Observed behavior: the user is deprovisioned, but the REST API call never completes so I keep getting “InProgress” every 5 seconds until the Runbook token times out. Expected behavior: the REST API call completes once the user is deprovisioned.

Note: same call (‘sudo waagent -deprovision+user -force’) completes OK when run via SSH.

@o-l-a-v you are correct - thank you for pointing out

@abaymar Yes, agreed. We have a work item for this in our queue, but at this point we are focused on other tasks. Once we get to it I’ll post to #1792
