Set-SPPassPhrase: Error deploying administration application pool credentials. Another deployment may be active.

Problem: Got this error message when trying to change pass-phrase in a SharePoint 2013 farm:

Set-SPPassPhrase: Error deploying administration application pool credentials. Another deployment may be active. an object of the type Microsoft.SharePoint.Administration.SPMasterPassphraseDeploymentJobDefinition named "Job-admin-passphrase-change" already exists under the parent Microsoft.SharePoint.Administration.SPTimerJobService named "SPTimerV4". Rename your object or delete the existing object.

Solution: Clear SharePoint Configuration cache on all SharePoint Servers! Make sure SharePoint timer job is successfully started after clearing SharePoint configuration cache.

If you still experience the trouble, Delete the timer job and try again with your pass phrase change:

#Get the passphrase change timer job
$job = Get-sptimerjob job-admin-passphrase-change
#Output to screen
$job 
#Delete the timer job
$job.Delete()
