    Deploying a .wsp-file on SharePoint 2010, you may stumble over the next error message:
Install-SPSolution : Admin SVC must be running in order to create deployment timer job.

How have I got it? In SharePoint 2010 Management Shell I had successfully performed the following command to upload my SP2010 solution package into the system:

Add-SPSolution "C:\WSPDeployment\My2010Solution.wsp"

Then I had tried to run the next one to deploy the uploaded solution:

Install-SPSolution -Identity My2010Solution.wsp -GACDeployment -AllWebApplications

and after that I received the mentioned error.

Now, how to fix it. It’s needed to go to Administrative Tools -> Services and manually start the service called SharePoint 2010 Administration. Not to have such error in the future, change service’s Startup type to Automatic.

Having made this, I run Install-SPSolution once again and received a new error:
A deployment or retraction is already under way for the solution “My2010Solution.wsp”, and only one deployment or retraction at a time is supported.

It looked like an appropriate deployment job was added to the list of timer jobs, but the attempt to execute the job failed due to unstarted SharePoint 2010 Administration service. I found a solution here. We need to cancel the deployment job by performing the next steps:

1. Grab the id of the job by running the command: stsadm -o enumdeployments. Yep, the old friend, stsadm helps us out 🙂 Look through the result, find the required deployment job and grab the id. The result should look like

   C:\...red\Web Server Extensions\14\BIN>stsadm -o enumdeployments
   
   <Deployments Count="1">
      <Deployment JobId="2de92a5f-6c70-4325-ac2c-293a34dd9c67">
         <Title>Microsoft SharePoint Foundation Solution Deployment for "My2010Solution.wsp"</Title>
         <Type>Deployment</Type>
         <State>Pending</State>
         <Schedule>12/16/2011 3:47 PM</Schedule>
         <File>My2010Solution.wsp</File>
         <ServerType>Front-end Web server</ServerType>
         <Target>http://mySPServer/</Target>
      </Deployment>
   </Deployments>
   

2. Using the found id, cancel the job by means of the command stsadm-o canceldeployment-id “found Job id”. For example, in my case it’s

   stsadm -o canceldeployment -id "2de92a5f-6c70-4325-ac2c-293a34dd9c67"

   If it succeed you get “Operation completed successfully” message.

3. Run again stsadm -o enumdeployments to make sure that the given deployment job disappeared

Ok, now you can repeat deployment of your solution, run Install-SPSolution again. The issues was overcome in my case.
