Questions[kivy](ubuntu)

I'm trying to install Kivy, a Python Framework, but run into problems using pip.

Following the instructions on https://kivy.org/doc/stable/installation/installation-linux.html I get the following error.

Can someone help? What Input should I post here to resolve the issue?

$ python -m pip install --upgrade --user pip setuptools virtualenv

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

I am trying to create a Python app (using Kivy). I am at the stage where I would like to push it to my device, however I keep getting an error message:

ModuleNotFoundError: No module named '_csv'

Here is a link to a trimmed version of the log output (trimmed to the error: https://gist.github.com/dipeshjoshi01/d3ec50995acb2e4b4f89e0c7fccb9b82) which shows this.

I've looked around and it looks like my Python wasn't installed correctly on my virtual Ubuntu device, and it is missing the "_csv.py" file. But it also looks like this can't be installed.

From what I have read online, people recommend to uninstall, then reinstall python again as the version could be corrupted. I am a bit nervous about doing this though, incase it messes up the Python that should be there.

Can anyone talk me through how I would go about getting this file back onto my device (either how I should un/reinstall Python, or an alternative way).

Apologies if this is a basic question, I'm very new to Ubuntu, but looking forward to learning more about it! If it helps, I am running Python3.6.

I have a working kivy application, and am trying to turn it into an app using buildozer (using Ubuntu 18.04 in virtualbox on a windows PC). I created a buildozer.spec file using buildozer init, and then I ran buildozer -v android debug in terminal. After a few minutes, I got the long error message below. Above that error message, I found the line

ERROR: Could not find a version that satisfies the requirement csv (from -r requirements.txt (line 4)) (from versions: none)

I take it that the (from versions: none) is the problem - where do I fix that?

I am trying to convert python kivy code to android app using buildozer, I have been installed all thing see the image

I have been trying to run my .py file using ubuntu server and fluxbox. I wanted to make that my file will run after fluxbox minimal desktop starts.

But when i edit ~/.fluxbox/startup file, the X automatically exits without any error.

My .fluxbox/startup file looks like:

...
exec fluxbox & /home/user/KivyProject/run
...

when i delete /home/user/KivyProject/run fluxbox works normally.

My run script looks like:

python /home/user/KivyProject/main.py

my .py file looks like:

from kivy.app import App
from kivy.uix.button import Button
class TestApp(App):
    def build(self):
        return Button(text='Hello World')
TestApp().run()

What am i doing wrong? Where should i put the path to my script in order to run it after X starts?

Thanks in advance for every reply!
Cheers!
