+# Unable to create Jupyter notebook in Azure HDInsight
+
+This article describes troubleshooting steps and possible resolutions for issues when interacting with Azure HDInsight clusters.
+
+## Issue
+
+When starting a Jupyter notebook, you receive an error message that contains:
+
+```error
+Cannot convert notebook to v5 because that version doesn't exist
+```
+
+## Cause
+
+A version mismatch.
+
+## Resolution
+
+1. Use [ssh command](../hdinsight-hadoop-linux-use-ssh-unix.md) to connect to your cluster. Edit the command below by replacing CLUSTERNAME with the name of your cluster, and then enter the command:
+
+    ```cmd
+    ssh [email protected]
+    ```
+
+1. Open `_version.py` by executing the following command:
+
+    ```bash
+    sudo nano /usr/bin/anaconda/lib/python2.7/site-packages/nbformat/_version.py
+    ```
+
+1. Change **5** to **4** so the modified line appears as follows:
+
+    ```python
+    version_info = (4, 0, 3)
+    ```
+
+    Save changes by entering **Ctrl + X**, **Y**, **Enter**.
+
+1. From a web browser, navigate to `https://CLUSTERNAME.azurehdinsight.net`, where `CLUSTERNAME` is the name of your cluster.
+
+1. Select **Jupyter** and then restart the service.
