As other told, the right way is probably to compile it yourself (or use
pyenv, but I don't like pyenv "shims", I prefer to keep it simple).
I'm using a bash function [1] to easily recompile needed Pythons (I test
some projects with Python 3.5 to 3.9), but it's not that hard without my
bash function:
apt install make build-essential libbz2-dev liblzma-dev libssl-dev
llvm libreadline-dev libncurses5-dev libffi-dev zlib1g-dev tk-dev
libsqlite3-dev xz-utils
wget the version you want from https://www.python.org/ftp/python
tar -xzf it
./configure --prefix=$HOME/.local/
make -j $(nproc)
make altinstall
You'll get a `python3.8` binary in ~/.local/bin, you can create venvs
with it as:
python3.8 -m venv the_venv_path
