Hi @DouglasMoore,

I would like to provide some clarification regarding the commands mentioned in your post about DBR 15.1 or above. Contrary to what was stated, these commands are indeed necessary. Recently, when attempting to install UCX via the web terminal on my cluster, I encountered specific issues that were resolved by executing these commands.

The recommended flow is as follows:

1. Begin by installing the required UCX dependencies and setting up the Python virtual environment:

apt-get update
apt install -y python3.10-venv
unset DATABRICKS_RUNTIME_VERSION

2. Next, download and install the Databricks CLI:

curl -fsSL https://raw.githubusercontent.com/databricks/setup-cli/main/install.sh | sh

3. Configure the Databricks CLI to authenticate with the correct workspace, adding the hostname and PAT token:

export DATABRICKS_HOST=https://<hostname>
export DATABRICKS_TOKEN=<PAT>

4. Finally, proceed to install UCX:

databricks labs install ucx

Following these steps ensures the correct installation of UCX. It's important to note that failure to provide the Databricks hostname and PAT token, even with DBR 15.1 or above, can lead to installation failures on Azure with AWS-linked validation errors.
