#13291 — How to install older python version on Debian

Dear Debian Python,

I would like to install older python (version 3.6) on my venv environment

$ inxi -S
System:    Host: debian Kernel: 5.10.0-4-amd64 x86_64 bits: 64 Desktop: 
KDE Plasma 5.20.5
            Distro: Debian GNU/Linux bullseye/sid

(venv)$ python --version
Python 3.9.2

on fedora I can easily do something like this[1], but on debian I 
wondering how I can achieve the same thing, as it look like and I guess 
older python are not available directly on repository

$ sudo apt-cache pkgnames python3.
python3.9-venv
python3.9-examples
python3.9-full
python3.9-dbg
python3.9-dev
python3.9-doc
python3.9
python3.9-minimal

If my guest are right. Could you suggest me a solution how to have 
multiple python version so I can load inside venv?

As I understand the question is it

} What is the equivalent of
}   sudo dnf install python36
} so that I can do
}   virtualenv --python=/usr/bin/python3.6 foo
}   source foo/bin/activate

This only works as long as the version you need is in the repo. It's
expected that a 2019 distro with 3.7 as the default may also include 3.6,
which is somewhat different from what you expect here.

Build it manually and install it somewhere in your user directory or use
pyenv.

Hello,

I’d suggest you build it from source (python.org/ftp... with the needed version) as an additional python version, and then create your venv using the 3.6.

You can dm me if you might need more details.

Best regards,
Balazs

This would give a false suggestion that such a package works with packaged
modules.
