Expected behavior

Kolibri just starts.

User-facing consequences

I already have around 60gb worth of kolibri downloaded files. I just copied .kolibri folder from my old installations and paste it in new installation. This was working like a charm in the past. Now I don't know what is happening. It didn't even start. In ubuntu, It still works. So the problem is not with database. It is with Manjaro and kolibri combinations. It just misses some dependencies or something like that. I tried to search kolibri website to look for any dependencies list. But i couldn't find it. So please help me.

Steps to reproduce

Hi @nemoece - apologies, we should update this prior to the next patch release of 0.15, but Kolibri is not compatible with Python 3.10 yet. I recommend running it using Python 3.9 instead.

I've opened a pull request to make sure that from 0.15.2 onwards, Kolibri will properly show it is incompatible with Python 3.10.

Thanks for the info @rtibbles . Is there any specific command i can give so that kolibri run on python 3.9
Thanks for your help.

Make sure you have Python 3.9 installed on your system, then make a Python virtual environment using that version of Python.
