# Troubleshooting
+### Make command not found
+
+If you get the error `bash: make: command not found` then you need to install GNU make. Run `sudo apt update` and `sudo apt install make` to install.

### Docker Versions
If you get an error such as: `ERROR: Version in "./docker-compose.activemq.yml" is unsupported.`, then you need to upgrade Docker. Enter the command `make clean` before re-attempting to `make demo`.
