do not run STSADM in Powershell and for some reason it does not return any error and message and is not working
- with Command Prompt change dir to "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN\STSADM.EXE"
(optional) run below command and see the current probably stuck jobs
stsadm -o enumdeployments
stop **SharePoint 2010 administration ** service from services.msc
now run below command and all jobs will be run manually
stsadm -o execadmsvcjobs
results: note the last 2 WSPs which was sucked in my case :
Operation completed successfully.
