+### Debian Prerequisites
+
+I needed to install these:
+
+```shell
+sudo apt install libbz2-dev libssl-dev python3.11-dev build-essential
+```
+
+To regenerate the Mumble ICE client, I did need to install the ZeroC ICE
+Python package:
+```shell
+sudo mkdir -p /etc/apt/keyrings
+curl -fsSL https://download.zeroc.com/GPG-KEY-zeroc-release-B6391CB2CFBA643D | sudo gpg --dearmor -o /etc/apt/keyrings/zeroc.gpg
+echo'deb [signed-by=/etc/apt/keyrings/zeroc.gpg] https://download.zeroc.com/ice/3.7/debian12 stable main' | sudo tee /etc/apt/sources.list.d/zeroc-ice-3.7.list
+sudo apt update
+sudo apt install python3-zeroc-ice
+```
+
+## Further Information
+
+See the page about [ICE](https://wiki.mumble.info/wiki/Ice) at the Mumble
+wiki; it also includes detailed information about the PHP and Python
+clients, including how to update the client.
