+### LD_LIBRARY_PATH
+
+The default `LD_LIBRARY_PATH` environment variable is incorrectly set in the Ubuntu VM. As a result, GNU Radio might not be able to find the compiled OOT modules. Please do the following to correct this issue.
+
+Open BASH configuration file in VS Code.
+
+```
+$ code ~/.bashrc
+```
+
+Update the existing line setting `LD_LIBRARY_PATH` as follows:
+
+```
+export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/lib/x86_64-linux-gnu/
+```
+
+Update the environment variables for your current terminal.
+
+```
+$ source ~/.bashrc
+```
+
+Make sure Linux is aware of any new OOT libraries:
+
+```
+$ sudo ldconfig
+```
+
+New terminal instances should will have the correct path, but you may need to perform this update every time you start the Ubuntu VM.
