It seems the version of SharePoint 2013 server on my dev machine was that of RTM. So I installed Service pack 1 from this link
Now I see the version is:
DisplayName : Microsoft SharePoint Server 2013
DisplayVersion : 15.0.4571.1502
I tried to install CU Update for Microsoft SharePoint Enterprise Server 2013 (KB3055009) , but I get the following message:
Update for Microsoft SharePoint Enterprise Server 2013 (KB3055009) 64-Bit Edition
---------------------------
The expected version of the product was not found on the system.
Using powershell script I got this information about my Products and Language Packs:
