Python coding from libertine ?

marek_python

Hi community,
I'd appreciated your thoughts on Python scripting on UT.
It's no surprise (now) to me that I can't install python packages via pip using terminal app since apt install python3-pip won't work.

Libertine is the way to go. I could install pip from what I remember but now I wonder how I go about scripts that use Python's socket module ? Will I be able to use scapy from within the container ? I'm getting tablet running UT so I'm thinking about my options.

Have you done any scripting using socket module ? How did you go about it ?

Yes, you should be able to install any Python module you need (so long as it is available to install on your device's architecture), with pip inside a Libertine container.

You may have an issue if you are trying to run something in perpetuity within the container as a server for example, or in some certain other situations, but in general most things should just work as normal. Just remember that there is no sudo in the container, and you should not install it in the container as it will cause things to break.

I'll probably run into some issues then. Because scapy won't run without superuser privileges. I gotta find a way.

@marek_python Why would scapy need that? But you can also run libertine-container-manager exec -i xenial -c bash for example to get a "root" (it's an unprivileged container, but in fakeroot mode in this case).

I'll defo try that. Thank you @dobey

Perhaps someone else will chime in with different experience.

Great news. I've just tried the fake root on my UT phone and scapy worked fine. No permission errors. Exciting times ahead.

Is it just on my phone or Terminal app crashes under screen lock ? It crashed twice after unlocking screen.

dobey

@marek_python The terminal app, and any child processes running in it, get paused when the screen locks. It shouldn't be crashing.

I'll be testing it and if it keeps crashing on my devices I'll report it as an issue so the community knows.

Disable app suspension for the terminal app on the tweak tool if you want.
Also, if you plan to create apps, you can try Seabass. It's a great code editor and supports creating a libertine container for building via clickable.
