Инструмент репо Android не работает с python2

В моем Dockerfile есть python3, и я получаю:

RUN repo init -u https://android.googlesource.com/platform/manifest
 ---> Running in f3adc38c2aac
/usr/bin/env: 'python': No such file or directory

Если я устанавливаю python, я получаю эту ошибку:

Step 6/7 : RUN repo init -u https://android.googlesource.com/platform/manifest
 ---> Running in 9c03e1b95c0f
repo: warning: Python 2 is no longer supported; Please upgrade to Python 3.6+.

Репо скачивается так:

RUN mkdir -p /android_tools \
&& curl https://storage.googleapis.com/git-repo-downloads/repo > /android_tools/repo \
&& chmod a+x /android_tools/repo
