Plugin installation error

[deniskonovalov64]

Execute these commands:

# source /opt/netbox/venv/bin/activate
(venv) # pip3 install nextbox-ui-plugin

And it gives me this error:

ERROR: Could not find a version that satisfies the requirement netbox-ui-plugin (from versions: none)
ERROR: No matching distribution found for netbox-ui-plugin

Can you suggest what can be done in this case?

ubuntu 20.04.5 LTS

pyhton3 -V
python 3.8.10

pip3 -V
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)

I'm sorry I was inattentive

There is a typo in the plugin name in your PLUGINS list. It should be nextbox-ui-plugin.

PLUGINSВ вашем списке опечатка в названии плагина . Это должно быть nextbox-ui-plugin.

Yes, I saw an error, so I closed this question, but thanks anyway)
