Mumo runs into RuntimeError; ends up not running #28

What happened?

When I try to run ./mumo.py, it almost instantly jumps back into my main terminal prompt.

Did you install python3-zeroc-ice (as listed in the requirements)? That should include the ice lib files that it says can't be opened.

python3-zeroc-ice is installed. Running sudo apt install python3-zeroc-ice returns "python3-zeroc-ice is already the newest version (3.7.8-2.1+b1)."

In the ini you set

slicedirs = /usr/share/slice;/usr/share/Ice/slice

Do you see/Can you located Ice/SliceChecksumDict.ice somewhere in there?

Kissaki commented 5 months ago

I don't see it in https://packages.debian.org/bookworm/amd64/python3-zeroc-ice/filelist

so maybe it's no longer part of that deb package.

Kissaki commented 5 months ago

It's part of zeroc-ice-slice

https://packages.debian.org/bookworm/all/zeroc-ice-slice/filelist

/usr/share/ice/slice/Ice/SliceChecksumDict.ice

So /usr/share/ice/slice seems fitting.

Do you have that file under that path?

Is the package zeroc-ice-slice installed?

Looks like the first does not depend on the latter. So I would expect installing it to fix it.

On Ubuntu 10 it looks like I installed it manually too.

Kissaki commented 5 months ago

In the README I added zeroc-ice-slice as a requirement.

Please confirm whether that fixes your issue.

AlexPewMaster commented 5 months ago

Installing the package zeroc-ice-slice seemed to fix the issue! I do have another question though: How do I stop Mumo? I ran python3 mumo.py and it's running in the background. What's the proper way to stop it?

Kissaki commented 5 months ago

The config file has a pidfile setting - https://github.com/mumble-voip/mumo/blob/master/mumo.ini#L45-L46

so that file (mumo.pid by default) should be created, and contain the process ID. You can shut down the process through that process ID.

I would expect the following to work

kill `cat mumo.pid`
