Can't get Iris to work

General
1

Hi all,
I desperately need your help. I am not able to geht Iris to work on my Raspberry Pi 4.
Mopidy is installed correctly and appears on the IP address of my Raspi, port 6680.
Then i installed Mopidi-Iris via Python3 according to the instruction, but it doesn’t start Iris.
Tried a hundred times to uninstall and install Iris again, with always the same result.

Do you have any hints?

Staus of Mopidy:

It doesn’t seem to think Iris is installed. If you run this you should be able to tell if the package is installed.

sudo mopidyctl deps

Run this to see if your Iris configuration is being loaded.

sudo mopidyctl config

Hi, thanks for your help.
Think it has to do with my python installation. I have Python 2 and Python 3 both installed.
This is the output of sudo mopidyctl deps:

We only support Mopidy v3 which is a Python 3 application. Remove older versions.

Thanks for your input, your’re right.
Unfortunately I wasn’t aware of that, just used the default package sources of ma Raspbian Buster Installation.
Now I followed the instructions on docs.mopidy.com and added the right package sources, and it works!
Thank for your help!
