#CANNOT INSTALL PYTHON 2.7 UBUNTU UPGRADE#

You are lucky in a sense that with Ubuntu 12.04 being a former LTS (long-term support) version, you always have an option to apt-get upgrade your whole OS and jump directly to the next LTS release which would upgrade everything from OpenSSL to Python and its system-wide modules. Python versions 2.7.9+ and 3.4+ ship newer pip with them by default. In Ubuntu repositories, Python 2.7.9 first appeared in 15.04 (Vivid Vervet), and Python 3.4.2 in 14.10 (Utopic Unicorn), which means you cannot upgrade system Python safely without upgrading your whole OS components. To see it in Python interpreter: > import sslР В РІР‚СњР В РІР‚С›ttributeError: 'module' object has no attribute 'PROTOCOL_TLSv1_2'Р В РІР‚СњР В РІР‚С›nother part of the problem is that Python < 2.7.9 (or <3.4 in Python3) itself has ssl module that doesn't support PROTOCOL_TLSv1_2, so pip cannot use it, even if openssl was up-to-date.

So, both pip and the curl commands you've tried fail because the operating system's underlying OpenSSL library version is below 1.0.1 (see $ openssl version command) which does not support TLS 1.2 required. TLS v1.2 requires OpenSSL 1.0.1 (or later) to function, but a minimum of OpenSSL 1.0.2 is generally recommended.Р В РІР‚СњР вЂ™Р’В¬url's libcurl supports TLS 1.2 since curl version 7.34, but older curl versions should be able to connect only if you had OpenSSL version 1.0.2 (or later). But TLS 1.1 support isn't enough for pip any more. curl and pip (and wget) also depend on the system OpenSSL for establishing SSL connections (use $ openssl version command). Python for Linux uses the system-supplied OpenSSL lib. The error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version can be reproduced by running pip with -v (for verbosity), along with SSLError, No distributions found, Max retries exceeded messages. They will be older than what comes from pip though, some may not be found in Ubuntu repositories. Quick workaround: Ubuntu package utilities apt-cache and apt-get allow to search and install thousands of the common Python packages ( $ sudo apt-get install python-). When I tried to apply this solution as suggested,Р В РІР‚СњР вЂ™Р’В¬url: (35) error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version Likewise I couldn't install any Python package!
