If you combine the instructions for downloading legacyClient.sh from here: https://support.inductiveautomation.com/hc/en-us/articles/360047576471-Ignition-8-32-bit-Vision-Clients
with the modifications here: Linux java 17 opens and exports - #2 by Kevin.Herron
and install JDK 17 instead of JDK 21, you may be able to launch a Vision Client that way.
