Upgrade to Python 2.7.9 on Ubuntu 14.04 LTS, and make your own .deb package for deployment<\/h2>\nNeed to run your web app with Python 2.7.9, but server environment uses Ubuntu 14.04 LTS? Don\u2019t replace Python, leverage VirtualEnv instead!\n

<\/div>\nApril 5, 2015\n

\n\nI had this post hanging in my drafts on how I attempted to install a valid Python 2.7.9 runtime environment on Ubuntu 14.04 and make my own .deb package for easy re-deployment.\n\nIMPORTANT<\/strong>\u00a0This procedure isn\u2019t complete as I had to shift focus elsewhere. I might rework this article to adjust what\u2019s missing.\n\nWhile I understand that Ubuntu 14.04\u00a0will<\/a>\u00a0 remain<\/a>\u00a0using\u00a0Python 2.7.6<\/em>\u00a0internally, applications we run can be configured to use another python environment. Its what virtualenv is all about after all, isn\u2019t it.\n\nThis post attempts to install, and make an installable\u00a0.deb<\/em>\u00a0package of\u00a0Python 2.7.9<\/strong>\u00a0and is meant to be used by web applications without touching the system\u2019s python runtime.\n
<\/a>Why not replacing internal Python version?<\/h2>\nThe reason is simple. If you replace internal Python version, other softwares within the OS will have broken dependencies.\n\nI realized this while I wanted to upgrade the version and breaking an hard dependency I have on Salt Stack. Since many components within a given Ubuntu version relies on Python, it could break anything else. This is why I stopped working on the idea of replacing internally, but instead to configure VirtualEnv to use another version instead.\n\nIf you see procedures that shows you to replace telling you to use\u00a0update-alternatives<\/code>\u00a0to replace python, don\u2019t do it! Go instead learn how to run your own Python version in VirtualEnv.\n<\/a>Procedure<\/h2>\n\n Install build dependencies\n\nThose were the ones I ran last before a successful build on\u00a0Ubuntu 14.04 LTS<\/strong>, if you aren\u2019t using the same distribution, you might get a different list.\n<\/code><\/pre>\n apt-get install -y gcc-multilib g++-multilib libffi-dev libffi6 libffi6-dbg python-crypto python-mox3 python-pil python-ply libssl-dev zlib1g-dev libbz2-dev libexpat1-dev libbluetooth-dev libgdbm-dev dpkg-dev quilt autotools-dev libreadline-dev libtinfo-dev libncursesw5-dev tk-dev blt-dev libssl-dev zlib1g-dev libbz2-dev libexpat1-dev libbluetooth-dev libsqlite3-dev libgpm2 mime-support netbase net-tools bzip2<\/code><\/pre>\n<\/li>\n Get Python sources and compile\n<\/code><\/pre>\n\n \n<\/div>\n\nwget https:\/\/www.python.org\/ftp\/python\/2.7.9\/Python-2.7.9.tgz<\/span><\/div>\n<\/div><\/li>\n \n<\/div>\n\ntar xfz Python-2.7<\/span>\n.9<\/span>.tgz<\/div>\n<\/div><\/li>\n \n<\/div>\n\ncd Python-2.7<\/span>\n.9<\/span>\/<\/div>\n<\/div><\/li>\n \n<\/div>\n\n.\/configure –prefix \/usr\/local\/lib\/python2.7<\/span>\n.9<\/span> –enable-ipv6<\/div>\n<\/div><\/li>\n \n<\/div>\n\nmake<\/div>\n<\/div><\/li>\n \n<\/div>\n\nmake install<\/div>\n<\/div><\/li>\n<\/ol>\n<\/li>\n Test if the version works\n<\/code><\/pre>\n\n \n<\/div>\n\n\/usr\/local\/lib\/python2.7<\/span>\n.9<\/span>\/bin\/python -V<\/div>\n<\/div><\/li>\n \n<\/div>\n\nPython 2.7<\/span>\n.9<\/span><\/div>\n<\/div><\/li>\n<\/ol>\n<\/li>\n Then prepare package through FPM\n<\/code><\/pre>\n\n \n<\/div>\n\napt-get install -y ruby-dev gcc<\/div>\n<\/div><\/li>\n \n<\/div>\n\ngem install fpm<\/div>\n<\/div><\/li>\n \n<\/div>\n\n…<\/div>\n<\/div><\/li>\n<\/ol>\n<\/li>\n<\/ol>\nIts basically about creating a .deb based on your new runtime setup.
