Solution Update or Retract issue in SharePoint 2010

Issue Description:


Last week I ran into one issue when I tried to Update or Retract a solution  in SharePoint 2010.

When I tried to update/retract one of the solution in the sp2010,the Power shell command  has executed but when I went into Manage Farm Solutions, there the solution was showing the status as the deployment has been scheduled from 5/3/2012 05:53 AM and it won’t complete.

Resolution:

Verified the services.msc and found that SharePoint Timer service was  stopped and restarted the service and tried updating the solution and executed successfuly and updated the solution.
