VPN or Virtual Private Network is defined as an encrypted path between a device and a network over the Internet. VPNs ensure the security of the transmitted data by offering encrypted channels for data flow. In this way, the communication between two participating entities remains secure. Moreover, it also prevents any intruder from eavesdropping the traffic flowing from one end to another. VPN software is available for all the operating systems, therefore, you can conveniently install and use them.
To manage these VPNs, there is a dedicated protocol known as OpenVPN. It acts as an interface between the VPN server and the client. If you have this protocol installed on your operating system, then you can easily install any VPN software of your choice on it.
In this article, we will show you how to find out if OpenVPN is installed on Linux Mint 20 or not which is also a pre-requisite for installing any VPN software on it.
Verify whether OpenVPN Protocol is Installed on Linux Mint 20
For verifying if the OpenVPN protocol is installed on Linux Mint 20 or not, you will need to perform the following steps:

It is advisable to update and upgrade your system before checking if OpenVPN is installed on Linux Mint 20 or not because some corrupt or outdated packages might cause a hindrance in displaying all the installed protocols. For updating your Linux Mint 20, type the following command in your terminal and then press the Enter key:
