OpenSSL is an open-source toolkit for Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols, as well as a cryptography library. The purpose of this article is to show how to update OpenSSL on the Ubuntu® operating system.
Check the current OpenSSL version
To verify the OpenSSL installation and version, you can execute the following command:
openssl version -a
Update or install OpenSSL
In case OpenSSL is not installed on your system, use this step to install or update it to the newest version of the OpenSSL package.
Run the following instruction:
sudo apt-get install openssl
Note: If the result line is 0 packages updated, there are no available updates for the OpenSSL package.
Update all system packages
To update all system packages, not only OpenSSL, you need to update the list of available upgrades:
sudo apt-get update
To install all available new versions, run the command:
sudo apt-get upgrade
