Debian 12 pip pipx install error

First, I wasn't sure which section to put this in. It's not a problem with the Debian package but IS a problem with Debian 12. So mods, if this is the wrong spot, feel free to move it. Sorry
Been using SAB on my Debian 11 box for a few years with zero problems. I was able to follow all the instructions just fine and it has been humming along.
Before I upgrade my main server to Debian 12, I installed it on a test system and am installing all the programs I use (Plex, Emby, Sonarr, Radarr and SAB) to make sure I won't break anything.
Everything was going perfectly until I got to SAB
I know that Debian made some changes to the pip stuff (pipx now) and when trying to install SAB, I ran into this problem:
Code: Select all
pip install --upgrade -r requirements.txt
error: externally-managed-environment
× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.
If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.
If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.
See /usr/share/doc/python3.11/README.venv for more information.
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
While I -have- been using Linux for a few years, I'm by no means an expert and can't figure out how to proceed. Should I use '--break-system-packages' or the fix right in front of my eyes?
Code: Select all
python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip.
Just want to go the best route to ensure SAB works 100%. I understand what the Debian devs are saying about why they changed things...... isolating pip stuff so it doesn't break some critical python package....... but in the years I've been using Debian 10/11, the "old way" with pip never broke anything.

So I tried following the instructions in the README.venv file and failed miserably. I'm too embarrassed to type out what I tried so does anyone know the correct commands and folders to create to get this working?

Yeah. That's food for discussion on different forums. In general, I see more Compartmentalization: docker, snap, flatpak, venv.
I bit the bullet and tried python venv for the first time ... and it wasn't difficult. See my notes on
viewtopic.php?t=26235
So I would go that way: venv. After all, Debian people can't be wrong!

Just 4 commands, and it works:
Code: Select all
root@e6118656fbc8:~# python3 -m venv ~/my-sabnzbd-venv
root@e6118656fbc8:~# source ~/my-sabnzbd-venv/bin/activate
(my-sabnzbd-venv) root@e6118656fbc8:~# python3 -m pip install -r /sabnzbd-4.0.2/requirements.txt
(my-sabnzbd-venv) root@e6118656fbc8:~# python3 /sabnzbd-4.0.2/SABnzbd.py
Note: change the directories to your needs

Full sequence, on a fresh debian:bookworm docker, with the venv inside the SABnzbd directory ... maybe cleaner to do it that way:
Preparation
Code: Select all
apt update
apt install python3-venv wget -y
wget https://github.com/sabnzbd/sabnzbd/releases/download/4.0.2/SABnzbd-4.0.2-src.tar.gz
tar xvzf SABnzbd-4.0.2-src.tar.gz
cd SABnzbd-4.0.2
python3 -m venv my-sabnzbd-venv
Activate the venv, install requirements, and run SABnzbd:
Code: Select all
source my-sabnzbd-venv/bin/activate
python3 -m pip install -r requirements.txt
python3 SABnzbd.py -b0 -l2
Leave the venv:
Next time run it like this
Code: Select all
source my-sabnzbd-venv/bin/activate
python3 SABnzbd.py -b0 -l2

Thank you so much, that worked! I wonder if this can be added to the official install documentation? (Maybe a special section for Debian 12 since they have switched to using venv's for pip?)
Next question, how do I make this auto-start at boot? On my Debian 11 system, in the 'Startup Applications' applet, I have an entry for 'SABNZBD' and this is the command I use:
Code: Select all
/usr/bin/python3 /mnt/m2ssd/sabnzbd/SABnzbd.py

Ubuntu 23.04 also requires it.
And, yes, it must be in the documentation. And possibly a script in the SAB scource code that takes care of it?
how do I make this auto-start at boot?
Two ways:
* install the SABnzbd PPA (see
https://sabnzbd.org/wiki/installation/i ... buntu-repo) and follow that instruction to make sab auto-start. Then in /etc/init.d/sabnzbdplus change DAEMON= to something you want
* ugly: use crontab, with a line like:
So: after reboot, sleep 60 second, then start script

Whoops, my bad. I meant to say that the way I'm launching SAB at boot time now (via the 'Startup Applications' applet) in Debian 11 works perfectly. I can't figure out how to get SAB to auto-start at boot now that Debian 12 makes you use a pip venv.

I don't know 'Startup Applications', so I can't help with that.

No worries. If I type these 2 commands, individually:
Code: Select all
source my-sabnzbd-venv/bin/activate
python3 SABnzbd.py -b0 -l2
..... SAB works perfectly. I just need to find a way to automate typing those 2 commands at boot time.

You can simply create a shell script and execute at boot
