I was trying to add .net 3.5 features in a (Remote) Windows 2012 server. But I am getting the following exception.
Do you need to specify an alternate source path? One or more installation selections are missing source files on the destination server. The server will try to get missing source files from Windows Update, or from a location that is specified by Group Policy. You can also click the “Specify an alternate source path” link on this page to provide a valid location for the source files.
I have tried to download and install using setup of framework 3.5 and that also failed.
I have seen several workarounds for this from the below URL

Is it possible to add .net 3.5 without using Installation media(of OS)
Any help on this would be greatly appreciated.
Reboot your computer and try installing the NET Framework. If still getting the same error message then try following the below-given steps. Open CMD (Command Prompt) in administrator mode. In the command prompt window, type the following command “net stop wuauserv” and press the enter button to stop the service.
You do not have sufficient privileges to complete this operation for all users of this computer. Log on as an administrator and rerun Setup. You must be an administrator on the computer to install the . NET Framework.
The only solution for this problem is to simply update your Windows 10. It is advised to check for Windows Updates even if you are on the latest version of Windows 10. Since the problem is caused by incompatible operating system, installing all the available Windows 10 updates will most likely resolve the issue.
I have solved this by Selecting "Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS)" Checkbox in Edit Group policy screen, as suggested in method 2 of the above URL
