    --prefix=/usr/local \
    --libdir=/lib \

After that the version of OpenSSL you downloaded should be installed on the directory /usr/local/ssl.

Ubuntu default OpenSSL version is installed in the /usr/lib/ssl and it’s where apps that need to use SSL look by default

You’ll need to reference the version you installed.

Run the commands below option Ubuntu default man page

sudo nano /etc/manpath.config

Then add the following:

MANPATH_MAP     /usr/local/ssl/bin      /usr/local/ssl/man

Then run the commands below to update the manual database…

sudo mandb

You can also update the execution path to include the new location for OpenSSL. run the commands below to open Ubuntu environment configuration file.

sudo nano /etc/environment

Then add the /usr/local/ssh/bin as shown in the line below…. Use the exact path as shown…

PATH="/usr/local/sbin:/usr/local/bin:/usr/local/ssl/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"

TSL

June 30, 2018 => On that date all remaining python.org sites, including PyPI, will no longer support TSL 1.0 and 1.1. Older Python versions that do not implement TLSv1.2 will be prohibited from accessing PyPI.

check your version of python supports TLS1.2:

python -c "import json, urllib2; print json.load(urllib2.urlopen('https://www.howsmyssl.com/a/check'))['tls_version']"

Python 2.7.1+ (Ubuntu 11.04) => TLS 1.0
Python 2.7.15 => TLS 1.3

Update Python to 2.7.15

The package “python2.7” exists in the Ubuntu repositories but it’s not up-to-date.

If you want the latest version of Python, you’ll have to install it from source.

version=2.7.15
mkdir -p /opt/python/packages/python/
cd /opt/python/packages/python/
wget --no-check-certificate https://www.python.org/ftp/python/$version/Python-$version.tgz
tar -xf Python-$version.tgz -C /opt/python/packages/python
ln -s /opt/python/packages/python/Python-2.7.15 /opt/python/packages/python/current
cd /opt/python/packages/python/current
./configure --prefix="/opt/python/builds/python/$version" --with-ssl
make && sudo make install
cd ..
rm /opt/python/packages/python/current
ln -s /opt/python/builds/python/2.7.15/ /opt/python/builds/python/current

Test

/opt/python/builds/python/2.7.15/bin/python -c 'import sys; print(".".join(map(str, sys.version_info[:3])))'

Link

sudo ln -s /opt/python/builds/python/2.7.15/bin/python /usr/bin/python2.7.15
python2.7.15 -V
sudo rm /usr/bin/python
sudo ln -s /opt/python/builds/python/2.7.15/bin/python /usr/bin/python

Solve problem [ ValueError: /usr/bin/python does not match the python default version. It must be reset to point to python2.7 ] on apt-get install

sudo rm /usr/bin/python
sudo ln -s /usr/bin/python2.7 /usr/bin/python

Solve problem [No module named 'lsb_release'] when lsb_release -a

sudo ln -s /usr/share/pyshared/lsb_release.py /usr/lib/python2.7/site-packages/lsb_release.py
