SharePoint WSP Solution Deployment Stuck at "Deploying"

Issue: SharePoint WSP Solution got stuck at "Deploying" stage for hours while trying to deploy using STSADM command in SharePoint 2007!

Same thing happened in SharePoint 2013 also:

Workarounds: 
Try these workarounds to fix the solution deployment stuck at "deploying" stage.

• Make sure all your WFE & DB Servers in the Farm has no Time zone different! Make them aligned!
• Try running: stsadm -o execadmsvcjobs as the first step!
• Cancel the deployment, Remove the WSP and Re-deploy: 
• stsadm -o enumdeployments - This will give the GUIDs of all solution in "Deploying" State. Cancel the deployment using stsadm -o canceldeployment <GUID> command. E.g.:
• stsadm -o canceldeployment -id "95823b2b-8c92-4d08-99d5-7cf14c7be602"
• Delete the stuck solution with stsdm -o deletesolution -name mysolution.wsp -override
• Redeploy the solution.
• Try deploying for a single web application rather all.
• Try Restarting Timer Job on all servers of the Farm. Restart SharePoint Timer Service on all Servers in the Farm
• Try Clear Config Cache : How to Clear SharePoint Configuration Cache using PowerShell 
• In "services on server", make sure "Microsoft SharePoint Foundation Workflow Timer Service" is running. If not, start it!
• Check "SharePoint Administration Service" in services console. If stopped, start it.
• If any one of your SharePoint Web front end server (where SharePoint web application is running) is turned-off, You may get into this issue. Either turn it ON or remove the server from the SharePoint server farm.
• As the last: Reboot the server! If nothing helps, have a look at the SharePoint logs/Event Log to check root cause.
