+The `./config.sh` will check .Net Core 3.x dependencies during runner configuration.  
 You might see something like this which indicate a dependency's missing.
 ```bash
 ./config.sh

    libunwind-x86_64.so.8 => not found
-Dependencies is missing for Dotnet Core 2.1
-Execute ./bin/installdependencies.sh to install any missing Dotnet Core 2.1 dependencies.
+Dependencies is missing for Dotnet Core 3.0
+Execute ./bin/installdependencies.sh to install any missing Dotnet Core 3.0 dependencies.
 ```
 You can easily correct the problem by executing `./bin/installdependencies.sh`.  
 The `installdependencies.sh` script should install all required dependencies on all supported Linux versions   
 > Note: The `installdependencies.sh` script will try to use the default package management mechanism on your Linux flavor (ex. `yum`/`apt-get`/`apt`). You might need to deal with error coming from the package management mechanism related to your setup, like [#1353](https://github.com/Microsoft/vsts-agent/issues/1353)
