How to set up a VPN on Linux Ubuntu in 2026

In 2026, the use of VPNs on Linux Ubuntu is becoming increasingly relevant. Users are looking for ways to bypass blocks, such as YouTube and TikTok, and to protect their privacy. In this article, I will share step-by-step instructions for setting up a VPN on Linux Ubuntu, as well as explain why it is needed and how to choose the right service.

What is a VPN and why is it needed on Linux Ubuntu?

Definition of VPN

A VPN, or virtual private network, is a technology that allows you to create a secure connection over the internet. It encrypts your data and hides your IP address, making your online presence more anonymous.

Advantages of using a VPN

Using a VPN on Linux Ubuntu has many advantages. First, there is security. Your data is protected from interception, especially when using public Wi-Fi networks. Second, a VPN allows you to bypass geographical blocks and censorship. For example, you can access content on YouTube or TikTok that is not available in your region.

How a VPN helps bypass blocks

A VPN helps bypass blocks by redirecting your internet traffic through a server in another country. This allows you to "fool" websites that check your location. For example, if you are in Russia and want to access content on the American YouTube, a VPN on Linux Ubuntu will help you do this.

How to choose a VPN for Linux Ubuntu?

Criteria for choosing a VPN

When choosing a VPN for Linux Ubuntu, pay attention to speed, security, and server availability. It is also important that the service supports the necessary protocols and has a good reputation. It is best to choose services that provide a transparent privacy policy and do not keep logs.

Comparison of protocols: WireGuard, OpenVPN, IKEv2

There are several VPN protocols, each with its advantages. WireGuard has become popular due to its speed and simplicity. OpenVPN offers a high level of security and flexibility but may be slower. IKEv2 is an excellent choice for mobile devices as it quickly restores the connection when the signal is lost.

Overview of popular VPN services

Among popular VPN services, NvoVPN stands out, offering a stable connection and high speed. Other options include NordVPN and ExpressVPN, which have also performed well on Linux Ubuntu. Make sure that the service you choose supports the required protocol and provides a sufficient number of servers.

Step-by-step instructions for setting up a VPN on Linux Ubuntu

Installing the necessary packages

The first step to setting up a VPN on Linux Ubuntu is to install the necessary packages. To do this, open the terminal and run the following commands:

sudo apt update

Configuring the VPN connection

After installing the packages, you will need to configure the VPN connection. Go to "Network Settings," select "Add VPN," and choose OpenVPN. Enter your VPN provider's details: server address, username, and password. I recommend using configuration files that can be downloaded from your provider's website.

Testing the connection

After setting up the connection, connect to the VPN and check your IP address. You can use a website like whatismyip.com for this. If your IP address has changed to the VPN server's address, everything is working correctly.

Troubleshooting VPN issues on Linux Ubuntu

Common errors and their fixes

Sometimes users encounter errors when connecting to a VPN. This is often related to incorrect settings or outdated packages. Make sure all packages are updated and try restarting the system.

Issues with provider blocking

Some providers may block VPN traffic. If you encounter this problem, try changing the protocol or server. For example, switching to IKEv2 may help bypass blocks.

Configuring DPI

DPI, or deep packet inspection, can affect the operation of your VPN. Some providers use DPI to detect and block VPN traffic. To bypass this, you can use traffic obfuscation or special ports that are not blocked.

Setting up VPN on old versions of Ubuntu

If you are using an old version of Ubuntu, the VPN installation process may differ slightly. For example, in Ubuntu 18.04 and earlier versions, additional dependencies may be required. Make sure you have all the necessary libraries installed, such asnetwork-manager andnetwork-manager-gnome.

To install the necessary packages, run the commands:

sudo apt update

After that, you will be able to configure the VPN through the Network Manager interface, as described earlier. If you encounter issues, try updating the system to the latest version or using alternative installation methods, such as Snap or Flatpak.

Using VPN on virtual machines

If you are running Ubuntu on a virtual machine, it is important to configure the VPN correctly to ensure security. Virtual machines may have their own network settings that can affect VPN operation. For example, make sure the virtual machine's network adapter is set to "Bridged" or "NAT" to ensure proper internet connectivity.

When installing VPN on a virtual machine, use the same steps as for a regular installation on a physical machine. It is also worth checking that the hypervisor is not blocking VPN traffic. In some cases, additional firewall or routing configuration may be required.

Testing and optimizing VPN connection

After setting up the VPN, it is important to test the speed and stability of the connection. Use tools such asping andtraceroute to check latency and connection stability. If you find low speed, try changing the server to one closer to your location. This can significantly improve performance.

It is also worth considering using additional features of your VPN service, such as ad blocking or DNS leak protection. These features will help improve your online presence and protect your privacy.
