MoOde audio install on BananaPi not working

[Flotec09!]

Hello everyone!
I have a banana PI M2plus running armbian bullseye. I wanted to install moOde with the help of this install instructions: https://github.com/moode-player/docs/blo...package.md

But when I try to run the first script, the following happens:

Code:

'https://dl.cloudsmith.io/public/moodeaudio/m8y/setup.deb.sh' \
| sudo -E distro=raspbian codename=bullseye bash
