[Solved] Ignoring ensurepip failure pip requires ssl/tls error in Debian Based (Ubuntu, Parrot, Debian, etc)

solve.sh

#!/bin/bash -e

# Note: it is a script to solve Ubuntu 18.04 LTS also Parrot OS 4.7
# different version of pythons compiling header confliction problems
#
# The idea is got from @JustAnotherArivist
# From URL: https://github.com/pyenv/pyenv/issues/945
#
# The script used in here is with slightly modifications
# to fit many different SSL header versions


# First under your home directory make OpenSSL library
# and extract useful package

mkdir ~/libssl1.0-dev
cd ~/libssl1.0-dev
apt-get download libssl1.0-dev
ar x libssl1.0-dev* data.tar.xz
tar -xf data.tar.xz --strip-components=2


# Second, specifically get your current system's SSL headers
# and make symbolic-links

libcrypto=$(ls /usr/lib/x86_64-linux-gnu/ | grep libcrypto.so......)
libssl=$(ls /usr/lib/x86_64-linux-gnu/ | grep libssl.so......)

ln -s /usr/lib/x86_64-linux-gnu/${libcrypto} ~/libssl1.0-dev/lib/x86_64-linux-gnu
ln -s /usr/lib/x86_64-linux-gnu/${libssl} ~/libssl1.0-dev/lib/x86_64-linux-gnu


# Set your CFLAGS LDFLAGS compile options
# And use pyenv install the python version <3.4.5 or <3.5.3

# Note: it is a one line command
# Please change the version of python that you want to compile
CFLAGS="-I${HOME}/libssl1.0-dev/include -I${HOME}/libssl1.0-dev/include/x86_64-linux-gnu" \
LDFLAGS="-L${HOME}/libssl1.0-dev/lib/x86_64-linux-gnu" \
pyenv install 3.5.0 # python version less then 2.7.13, 3.5.3 and 3.6+


# Remove tempor libssl1.0-dev direcotory
rm -rf ~/libssl1.0-dev
