Solution:
The solution is manual one, unless you find any automated solution.
It would stuck and display like below:
[command]D:DevOpsAgent_work_toolNuGet4.9.4x64nuget.exe restore D:DevOpsAgent_work2sAbC.sln -Verbosity Detailed -NonInteractive -ConfigFile D:DevOpsAgent_work2NugettempNuGet_247.config
So All you need to do is to go to your agent server and go to the directory
D:DevOpsAgent_work_toolNuGet4.9.4×64
and execute below command
restore D:DevOpsAgent_work2sAbC.sln -Verbosity Detailed -NonInteractive -ConfigFile D:DevOpsAgent_work2NugettempNuGet_247.config
It will restore the packages at once and you need to cancel the build and initiate again. Next time whole process will work like a charm. Please also make sure you have access to internet or source of the nuget packages.
