estou desenvolvendo um app com o python3 e o gui kivy no ubuntu 20LTS wls(windows sub-system linux) e me deparo com esse erro quando executo o script

script:

from kivy.app import App
from kivy.uix.button import Button

class inicio(App):
def build(self):
return Button(text = "ola mundo!!!")

inicio().run() 

error:

Amigo, provavelmente estão faltando dependências no teu Python. Executei o seu código aqui sem problemas... dei uma pesquisada e a sequência de comandos abaixo provavelmente irá resolver seu pepino:

pip install --upgrade pip wheel setuptools
pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew
pip install kivy.deps.gstreamer
pip install kivy.deps.angle
pip install kivy

Sem conseguir instalar tais dependências o código não irá executar. Não sei como ajudar pq não consegui replicar o erro, aqui instalou tudo de boa.

Está usando que distribuição e versão do Python?
