Why ProtonVPN on Zorin OS?

If you’re using Zorin OS and value strong privacy, ProtonVPN is a solid choice. ProtonVPN offers a strict no-logs policy, strong encryption, and a user-friendly interface that fits Linux environments well. Zorin OS is based on Ubuntu, so ProtonVPN’s Linux client works smoothly. In this guide, we’ll keep things practical and wallet-friendly, with steps that work for beginners and power users alike.

Prerequisites

A ProtonVPN account Free plan available, but paid plans unlock more servers and features
Zorin OS installed and updated System ≥ Ubuntu-based, 20.04 or newer recommended
Administrative sudo access on your Zorin OS machine
An active internet connection to download and install packages

Optional but helpful:

A wired or fast Wi-Fi connection for stable setup
A second device to verify your VPN IP location if you want cross-checks

Install ProtonVPN on Zorin OS

Follow these steps to install the ProtonVPN command-line tool CLI or the GNOME/KDE app depending on your preference.

Update your system

Open the Terminal and run:
- sudo apt update
- sudo apt upgrade -y
This ensures you have the latest package lists and security updates.

Add the ProtonVPN repository CLI method

Import ProtonVPN’s public key:
- sudo apt-key adv –keyserver hkp://keyserver.ubuntu.com:80 –recv-keys 8C1C4F3A
Add the ProtonVPN repository:
- sudo add-apt-repository ‘deb https://repo.protonvpn.com/debian stable main’
Update package lists again:
- sudo apt update

Install ProtonVPN CLI

sudo apt install protonvpn-cli
After installation, initialize with:
- protonvpn init
You’ll be guided to enter your ProtonVPN credentials and select a default protocol.

If you prefer the GUI protonvpn-cli uses a text-based interface, but you can also install the GUI

ProtonVPN provides GUI options via third-party packaging or via Flatpak/Snap in some configurations. The CLI method is reliable and commonly used on Linux. If you want a GUI, you can explore:
- Flatpak: flatpak install –user protonvpn
- Snap: sudo snap install protonvpn

Alternative: Install via Debian package if available

Visit protonvpn.com to grab the latest .deb package and install with:
- sudo dpkg -i protonvpn-release.deb
- sudo apt update
- sudo apt install protonvpn-cli

Verify installation

Note: ProtonVPN periodically updates its install methods. If you hit a snag, check ProtonVPN’s official Linux setup guide, which is kept up to date.

Quick Start: Connect to ProtonVPN

Log in
- protonvpn login
- Enter your ProtonVPN credentials
Connect to a server
- protonvpn connect
- Or specify a country/server: protonvpn connect us-free-1
Check your connection
- protonvpn status
- curl ifconfig.me to verify your IP address has changed

Optional: Use a specific protocol Why is nordvpn blocking my internet connection heres how to fix it

Protocol choices include OpenVPN UDP/TCP, WireGuard recommended for speed, and IKEv2. To set a protocol:
- protonvpn configure
- Choose WireGuard for best performance in many regions
- You can also specify while connecting: protonvpn c –protocol UDP

Advanced Configuration

Kill Switch and Network Lock

The Kill Switch prevents traffic from leaking if the VPN disconnects.
Enable:
- protonvpn kill
- protonvpn connect
Practical notes:
- The Linux Kill Switch can sometimes block legitimate traffic if misconfigured. Test by disconnecting VPN and ensuring no traffic leaks before relying on it.

Auto-Connect and Startup Settings

To start ProtonVPN on boot, you can add a systemd service or use the built-in auto-connect options if provided by the CLI:
- Create a systemd service to start on boot:
  - sudo nano /etc/systemd/system/protonvpn-autostart.service
  - Add the service unit that runs at boot to connect to a preferred server
  - sudo systemctl enable protonvpn-autostart
Alternatively, you can add a startup script in your desktop environment to run:
- protonvpn connect
This makes sure you’re protected right away when you log in.

DNS Settings with ProtonVPN

ProtonVPN can route DNS requests through its DNS servers for extra privacy.
To enable DNS handling:
- Ensure you’re connected to ProtonVPN
- Check DNS settings and verify no leaks using DNS leak test tools
- If needed, configure resolv.conf or systemd-resolved to prefer ProtonVPN DNS servers

Split Tunneling on Linux

Split tunneling allows you to choose which apps go through the VPN and which don’t.
ProtonVPN’s Linux client may support app-specific routing via the command line or config files:
- ProtonVPN split-tunnel options can be applied to route only specified traffic through the VPN.
Practical use cases:
- You stream content from a region while keeping critical business apps on the regular connection.

Performance and Privacy Tips

Choose servers closer to your location for lower latency. If you’re testing streaming or gaming, try multiple nearby servers for best results.
Use WireGuard protocol for faster speeds on most networks.
If your device uses a slower CPU, WireGuard generally provides better performance than OpenVPN.
Enable Secure Core on ProtonVPN if you want enhanced privacy when connecting through multiple servers note: may reduce speed due to routing.
For privacy-conscious users, always enable the Kill Switch and verify that DNS requests are being resolved by ProtonVPN’s servers.
Regularly update ProtonVPN CLI and Zorin OS packages to keep security patches current.

Troubleshooting Common Issues

Issue: ProtonVPN won’t connect
- Check your account status and credentials
- Run protonvpn status to view current connection status
- Ensure your firewall isn’t blocking VPN ports UDP 1194 or the port you selected
- Try a different server or switch protocol WireGuard vs OpenVPN
Issue: DNS leaks detected
- Ensure ProtonVPN DNS is active by reconnecting and verifying DNS settings
- Disable any conflicting DNS settings from your ISP or other VPNs
Issue: Slow speeds
- Test multiple servers, preferably near your location
- Try a different protocol WireGuard usually faster
- Check your local network performance without the VPN to determine if the issue is VPN-related
Issue: Kill Switch not blocking leaks
- Ensure the Kill Switch is enabled and tested
- Disable conflicting firewall rules that might bypass the VPN
Issue: Auto-connect not starting on boot
- Revisit the systemd service or startup script
- Check logs with journalctl to identify startup errors

Security Best Practices

Always use a trusted ProtonVPN server rather than free, low-trust options.
Enable the Kill Switch to prevent leaks if VPN drops.
Regularly update ProtonVPN and Zorin OS to close security gaps.
Use a strong ProtonVPN password and enable multi-factor authentication MFA on your Proton account.
Periodically test your IP address and DNS to confirm your traffic is protected.

Practical Tips for Windows, macOS, and Linux Users

The Linux experience can be more hands-on, but it’s also incredibly flexible. Embrace the CLI for reliability and control.
If you need a GUI experience, consider ProtonVPN’s official apps where available or use third-party Linux VPN GUI managers that support ProtonVPN.
For developers or power users, scripting VPN connections with systemd services can automate protection as soon as you log in.

Real-World Usage Scenarios

Streaming from a region-locked catalog: use a server in the target country, and test with your streaming app to confirm access.
Public Wi-Fi safety: enable ProtonVPN to encrypt traffic when connected to cafes or airports.
Remote work: keep sensitive work traffic on VPN while browsing non-work sites on the regular network if split tunneling is configured.
