OpenSSL, a robust open-source toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, is crucial for web servers, VPNs, and various other apps to ensure secure communications. Keeping OpenSSL updated is essential for security, as vulnerabilities can be discovered and exploited by malicious actors.
In this guide, we’ll walk you through the steps to update and upgrade OpenSSL on Ubuntu.
Let’s get started.
Step 1: Check the Current Version
Before updating OpenSSL, it’s a good idea to check the version you currently have installed:
openssl version
This command will display the current version of OpenSSL installed on your system.
Step 2: Update the Package Repository
Ensure your Ubuntu system’s package repository is up-to-date:
sudo apt update
This command fetches the latest package information from all configured sources.
Step 3: Upgrade OpenSSL
Now, upgrade OpenSSL to the latest version available in the repositories:
sudo apt install --only-upgrade openssl
This command will only upgrade OpenSSL without affecting other packages.
Step 4: Verify the Update
After the upgrade, check the OpenSSL version again to ensure it has been updated:
openssl version
Step 5: Restart Services (if necessary)
If you’re running services that depend on OpenSSL, such as a web server, you’ll need to restart them to use the updated version:
sudo systemctl restart apache2
Replace apache2 with the name of the service you’re using if it’s different.
Commands Mentioned
- openssl version – Displays the current version of OpenSSL.
- sudo apt update – Updates the package repository information.
- sudo apt install –only-upgrade openssl – Upgrades only the OpenSSL package.
- sudo systemctl restart apache2 – Restarts the Apache2 web server.
