I've recently installed OctoPrint 1.11.2 using OctoPi* 1.1.0 (build 2025.06.10.114348) image and added TouchUI Plugin for using my Raspi touch display.
When trying to start the script ./TouchUI-autostart/helpers/install it ends up with the error message "TouchUI was not found".
This happens, because the searched file "touchui.bundled.js" isn't located any more in a home directory but under /opt/octopi/oprint/lib/python3.11/site-packages/octoprint_touchui/static/js
The installation step "0-check-touchui" should be modified accordingly.
