Docker build failed

hellow~，I tried to use the code of the master branch to build the docker image, but it failed. I tried the code of 1.0.0 again and got the same error. Can anyone help me?
OS: Ubuntu 20.04
docker: 24.0.7

terminal logs:
```

Comienza con la línea 50 de Dockerfile y utilities/install.py, especialmente con la llamada a execute en la línea 38 y la invocación de yarn install en la línea 206. Reproduce la compilación con las versiones de Ubuntu y Docker indicadas, determina después por qué yarn no está disponible y verifica que la imagen de Docker se compile correctamente.
