-Apologies for the confusion. I'll now review the document you provided and include the relevant steps for setting up JupyterLab on a headless server.
+Certainly! I'll review the entire conversation and compare it with the attached document to build out a comprehensive step-by-step guide for setting up Conda and JupyterLab on a Debian 12 server. I'll include the additional details we've discussed, such as saving the `environment.yml` file, not launching Conda by default, and other helpful items.
