Raspberry Pi 5: mod-ui not working (?)

worik · October 12, 2024, 10:15pm

Friends

I have downloaded latest Patchbox OS and installed on a Raspberry Pi 5

Boots fine

Added modep modules from patchbox

(I had to do and update and full-upgrade before that worked)

Now mod-ui apears to be not working

tl;dr How is it possible to run mod-ui with python3 V 3.11? mod-ui` is in Python dependency hell and requires Python3 <= 3.10, or so I thought.

patch@patchbox:~ $ sudo systemctl status modep-mod-ui
● modep-mod-ui.service - MOD-UI

That looks like it is working, but there is nothing at port 8888

Running journalctl -u modep-mod-ui while systemctl restart modep-mod-ui gives:

A lot of failure, none of which means much to me.

ERROR:tornado4.application:Uncaught exception, closing connection

It had two tries, failed.

Then a third go, looking like it gave up on tornado.

Is this possible?

First you must make sure jack.service and modep-mod-host.service are running. Most usual reason is Jack service failing, try reconfiguring the Jack backend with higher buffers, if using USB audio card.

Excuse me

I was expecting to find mod-ui at port 8888, it is on 80.

It was working all along.

Thank you for attention. I am a little sheepish at being so silly!

Keep up the good work
