@iFreilicht and @nanguoyu Okay, this is pretty annoying. How would you guys feel about moving this Dockerfile to Ubuntu 20.04? I just checked and it looks like Python 3.8 is the default install there.

It would solve the issue of Python versions, and I personally want the newer version of Ubuntu. But if you guys want 18.04, I can maybe use the above curl hack.

Yes, you can move to Ubuntu 20.04. If Ubuntu 18.04 and Python 3.8 are essential to you, you can install Python from source and then use update-alternatives.

See this: https://gist.github.com/nanguoyu/0f67ce488da4b3ca179d3af0c8cdc699

Miniconda maybe also a choice.

RUN wget \
    https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh \
    && mkdir /root/.conda \
    && bash Miniconda3-latest-Linux-x86_64.sh -b \
    && rm -f Miniconda3-latest-Linux-x86_64.sh 
    
RUN pip3 install --upgrade pip &&\
	pip3 install setuptools>=41.0.0

@theJollySin I'm not using this dockerfile anyway, so I'm fine with you upgrading it :)
