New linux mint install help!

[j-wauters]

I have a clean new copy of linus mint installed on my machine. I am following the instructions and get stuck tring to install flask and netifaces. I get an error telling me I am installing in an external environment. I do not know how to correct this to compete my install. Can someone please help? Is there a good step by step guide to do a linux install that is not a raspberry PI.

Thank you!

without a screen shot of the error it's hard to tell whats up but I'll take a guess.
I think the python executable is in /usr/bin. To install packages for the base install try as root
sudo /usr/bin/python3 -m pip install flask
sudo /usr/bin/python3 -m pip install netifaces

I suspect you were not "sudo"ing

When I have tried to install the netifaces and flask I get an error like this:

$ sudo /usr/bin/python3 -m pip install netifaces
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/python3.12/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.

This is a new feature introduced rather recently. Do what it says and use the command:

pip install --break-system-packages Flask

This basically means pip behaves as before, no inherent increased danger.

You can drop the sudo and run slingbox_server.py as a regular user - this is much preferable, security and stability wise, in fact.
