Option 1: Upgrade OpenSSL (Existing Package)
To upgrade OpenSSL, use the “–only-upgrade” option with the apt command. Using this option, the user requires the sudo privileges:
sudo apt install --only-upgrade openssl
This upgrades OpenSSL to the latest version available, “3.0.11,” when writing this guide.
Option 2: Upgrade OpenSSL (Reinstall Package)
For upgrading OpenSSL, first, remove the existing OpenSSL package along with its configuration files via the “purge” utility:
sudo apt purge openssl
Next, remove any unused binaries and libraries associated with OpenSSL with the “autoremove” utility:
sudo apt autoremove
After that, users need to update the package list with the “apt” command:
sudo apt update
Finally, install the updated OpenSSL package:
sudo apt install openssl
After following either of these methods, your OpenSSL installation will be up-to-date.
