WSP Deployment error in Sharepoint 2013

Question

Hi,
When we are trying to deploy a WSP , below is the error message :

System.InvalidOperationException: Operation is not valid due to the current state of the object.
at Microsoft.SharePoint.Administration.SPConfigurationDatabase.Microsoft.SharePoint.Administration.ISPPersistedStoreProvider.GetParent(SPPersistedObject persistedObject)
at Microsoft.SharePoint.Administration.SPSolutionLanguagePack.get_DisplayName()
at Microsoft.SharePoint.Administration.SPSolutionLanguagePack.SetSolutionFile(SPFarmSolutionPackage solnPackage, String path, String solutionName, Boolean isRestore)
at Microsoft.SharePoint.Administration.SPSolution.AddLanguagePack(SPFarmSolutionPackage solnPackage, String path, UInt32 lcid, String name, Boolean isRestore)
at Microsoft.SharePoint.Administration.SPSolutionCollection.Add(String path, String name, UInt32 lcid, Boolean isRestore)
at Microsoft.SharePoint.PowerShell.SPCmdletAddSolution.CreateDataObject()
at Microsoft.SharePoint.PowerShell.SPNewCmdletBase`1.InternalProcessRecord()
at Microsoft.SharePoint.PowerShell.SPCmdlet.ProcessRecord()

Tried the below but could not help:

1) Restarted Timer service
2) Deployed using PowerSHell / Directly with Visual studio
3) Restarted IIS
4) Cleared Timer Job cache
5) Restarted server
6) Executed configuration wizard

Below are the other observations:

1. Event Viewer showing the error “The SharePoint Timer Service service terminated unexpectedly. It has done this 12 time(s). The following corrective action will be taken in 30000 milliseconds: Restart the service.” Every 3 mins.,, Event ID 7031
2. All the SP services are running as expected

Answer 1

Make sure the timer service running service account is placed in all server's Local Admin Group and make sure all the timer services are running from your SharePoint Farm.

$farm  = Get-SPFarm 
$disabledTimers = $farm.TimerService.Instances | where {$_.Status -ne "Online"} 
if ($disabledTimers -ne $null) 
{ 
    foreach ($timer in $disabledTimers) 
    { 
        Write-Host "Timer service instance on server " $timer.Server.Name " is not Online. Current status:" $timer.Status 
        Write-Host "Attempting to set the status of the service instance to online" 
        $timer.Status = [Microsoft.SharePoint.Administration.SPObjectStatus]::Online 
        $timer.Update() 
    } 
} 
else 
{ 
    Write-Host "All Timer Service Instances in the farm are online! No problems found" 
} 

Try clearing the config cache using below article script and then try again:
