How to package kivy and python to executable file in Ubuntu?

I have a Kivy application consisting of many Python and KV files. I want to create an executable so that it can be run in Ubuntu by an end user.

https://kivy.org/doc/stable/guide/packaging.html documentation mentions how to package in OS X and Windows, but there is no mention about Linux distributions.

Any help would be appreciated.

Here is a scheme that I have used. This script creates a .sh file to run the python/kivy app:

#!/usr/bin/tcsh

set APP_NAME="HandAndFoot"

# setup output
set OUTPUT="${APP_NAME}.sh"
if $#argv > 0 then
    set OUTPUT=$argv[1]
endif
echo "output will be to $OUTPUT"

# copy initial part of shell script into output file
cp ${APP_NAME}.basis $OUTPUT

# create a tar file of the Hand And Foot app
rm -f tmp.tar
tar cf app.tar *.py *.kv dropbox-trusted-certs.crt dialogs/*.py dialogs/*.kv dialogs/*.png resources/*.png resources/*.ico resources/default/*.png

# add the uuencoded version of the app to the end of the output file
uuencode app.tar app.tar >> $OUTPUT
chmod 755 $OUTPUT

# How does a file named "0" get created?? Don't know, but this gets rid of it
rm -f 0

The above script creates a HandAndFoot.sh that contains a tar of the app. In this case the app is called HandAndFoot. When the HandAndFoot.sh is run, it executes the main.py script of the app.

In addition to the above script, another file (in this case named HandAndFoot.basis) is required:

#!/bin/bash

APP_NAME="HandAndFoot"
PYTHON="NONE"
# check if python3 is installed
pyvers=$(python3 -V 2>&1)
echo $pyvers
regex="Python 3.*"
if [[ $pyvers =~ $regex ]]
then
    PYTHON="python3"
else
    # check if python is installed
    pyvers=$(python -V 2>&1)
    if [[ $pyvers =~ $regex ]]
    then
        PYTHON="python"
    fi
fi
if [[ $PYTHON != "NONE" ]]
then
    kivyimport=$(
    $PYTHON 2>&1  <<EOF
import kivy
EOF
    )
    kivyregex=".*Kivy .*"
    if ! [[ $kivyimport =~ $kivyregex ]]
    then
        echo "Python is installed, but Kivy is also required"
        echo "Use you package Manager or 'apt-get' to install Kivy"
        exit
    fi
else
    echo "Python and Kivy are not installed, but are required for the $APP_NAME app"
    echo "Use your Package Manager or 'apt-get' to install Python and Kivy"
    exit
fi

match=$(grep --text --line-number '^PAYLOAD:$' $0 | cut -d ':' -f 1)
payload_start=$((match + 1))
tail -n +$payload_start $0 | uudecode
rm -rf /tmp/$APP_NAME
mkdir /tmp/$APP_NAME
mv app.tar /tmp/$APP_NAME
cd /tmp/$APP_NAME
tar xvf app.tar
$PYTHON main.py &
exit



PAYLOAD:

The final script checks for Python and Kivy installation and runs main.py if python and kivy are installed. These scripts can be modified for different apps as needed.
