How To Install OpenSSL on Ubuntu 22.04 LTS

Install OpenSSL on Ubuntu 22.04

In this tutorial, we will show you how to install OpenSSL on Ubuntu 22.04 LTS. For those of you who didn’t know, OpenSSL is a widely-used open-source implementation of the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, which are used to secure communications over a network. It provides a library of cryptographic functions and command-line tools to use them, including symmetric ciphers, public-key ciphers, and hashing functions, as well as functions for managing digital certificates and certificate signing requests. OpenSSL is also used as a foundation for many other software libraries and tools, however, it’s important to keep your version of OpenSSL up-to-date to avoid known vulnerabilities.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the latest OpenSSL on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

Prerequisites

  • A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for OpenSSL.
  • A non-root sudo useror access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install OpenSSL on Ubuntu 22.04 LTS Jammy Jellyfish

Step 1. The first step is to update your system to the latest version of the package list. To do so, run the following commands:

sudo apt update
sudo apt install build-essential checkinstall zlib1g-dev

Step 2. Installing OpenSSL on Ubuntu 22.04 LTS.

By default, OpenSSL is not available on the Ubuntu base repository. Now run the following command below to download the latest source code of OpenSSL to your Ubuntu system:

cd /usr/local/src/
wget https://www.openssl.org/source/openssl-3.0.7.tar.gz

When the download is complete, proceed to extract the archive contents to your system:

tar -xf openssl-3.0.7.tar.gz
cd openssl-3.0.7

Before proceeding with the installation, change to the OpenSSL directory you extracted. To verify that you are in the correct location, list its contents by typing “ls“:

ls

Let’s check the installed version using the command below:

openssl version -a

Next, we compile from the source, and run the following command:

cd /usr/local/src/openssl-3.0.7
./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl shared zlib
make
make test

Output:

**********************************************************************

Please wait for the compiler to finish before continuing with the make install command:

make install

After successfully installing OpenSSL, continue by configuring the library paths:

cd /etc/ld.so.conf.d/
nano openssl-3.0.7.conf

Paste the OpenSSL library path directory:

/usr/local/ssl/lib64

Save and close the file, then reload the dynamic link using the command below:

sudo ldconfig -v

Step 3. Configure OpenSSL Binary.

We need to replace the OpenSSL binary found in /usr/bin/openssl or /bin/openssl with the new version in /usr/local/ssl/bin/openssl. First back up the existing files:

mv /usr/bin/c_rehash /usr/bin/c_rehash.bak
mv /usr/bin/openssl /usr/bin/openssl.bak

Next, edit the ‘/etc/environment‘ file using favorite your text editor:

nano /etc/environment

Add the new OpenSSL binary directory:

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

Save and close the file, then reloading the environment variable is necessary:

source /etc/environment
echo $PATH

Now we check the OpenSSL binary file again using the following command:

which openssl
