Upgrade OpenSSL on Ubuntu 14.04.2 LTS x64

Posted on Updated on

In this post I am going to tell you the steps to upgrade OpenSSL in Ubuntu 14.04 LTS x64.

Caution: Please make sure you have a complete backup of your current Ubuntu system before performing these steps.

Steps:

  1. By default Ubuntu 14.04 LTS comes with OpenSSL version 1.0.1j 15 Oct 2014. You can check this by typing the command “openssl version“.
  2. Install the build essential and check install packages by typing “sudo apt-get install checkinstall build-essential“.
  3. Download the OpenSSL version from the link. I downloaded the version 1.0.1u and extracted the files from tar.
  4. Run command “sudo ./config“.
  5. Then “sudo make“.
  6. Followed by “sudo make install“. This will install the OpenSSL in the “/usr/local/ssl“.
  7. Now go to “/usr/bin” directory and change the openssl name by typing “sudo mv openssl openssl_ORIG
  8. Next type command “sudo ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl/” which will create a symbolic link of the latest openssl binary.
  9. Reboot you’re Ubuntu.
  10. Now when you type the “openssl version” command you should get the latest version of OpenSSL; in this case it should be 1.0.1u.
