Step‑by‑Step Instructions
Prerequisites and Repository Setup
Before running Sudo apt install proton vpn-gnome-desktop, you need to add the ProtonVPN repository to your system. Open a terminal and execute the following commands to import the GPG key:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 5F5E5C4C
Next, add the repository URL to the APT sources list:
echo "deb https://repo.protonvpn.com/debian stable main" | sudo tee /etc/apt/sources.list.d/protonvpn.list
Refresh your package list:
sudo apt update
These steps prepare your system for a clean proton vpn linux install without dependency conflicts.
Installing the ProtonVPN GNOME Desktop Client
Now you’re ready to run the key command. Type:
sudo apt install protonvpn-gnome-desktop
During installation, the package manager will resolve all necessary dependencies. Once the installation completes, you’ll see the ProtonVPN icon in the system tray. Clicking it will prompt you to log in with your Proton account credentials.
If the command fails with a “Package not found” error, refer to the Unable to locate package ProtonVPN GNOME Desktop guide for troubleshooting steps.
After a successful install, launch the client by typing:
protonvpn-gnome
or clicking the icon. You should see a welcome screen that lets you choose a server, set a connection mode, and enable advanced options.
Logging In and Choosing a Server
Enter your ProtonVPN email and password. If you’re a free user, you’ll see a limited server list, whereas a paid subscription unlocks all servers worldwide. The client automatically recommends a server based on latency, but you can also select a specific region.
For users in the United States or Canada who want to stream U.S. content, choose a server in the U.S. Likewise, Europeans often prefer a server in the UK or Germany to access UK‑based services.
The client offers three modes: Standard, Stealth, and Secure Core. Standard is ideal for everyday browsing, while Stealth hides the VPN connection from ISP inspection. Secure Core routes traffic through multiple hops for maximum anonymity.
When you click “Connect,” the client establishes the tunnel. A status indicator will turn green, confirming a successful connection.
If you encounter a “connection timed out” error, the article Sudo apt install proton vpn-gnome-desktop provides solutions like disabling IPv6 or selecting a different server.
Verifying Your IP Address
Once connected, verify that your IP has changed. Open a browser and visit iplocation.net. You should see a new country and city that matches your chosen server.
Additionally, run curl https://api.ipify.org to see your public IP from the terminal. This quick check ensures your data is routed through the VPN.
For advanced users, ProtonVPN provides a CLI that can be used to connect, disconnect, and monitor VPN status directly from the console. This can be handy on headless servers.
To install the CLI, run:
sudo apt install protonvpn-cli
Then authenticate using protonvpn-cli login and connect with protonvpn-cli c. The CLI offers flags for stealth, secure core, and custom ports.
Troubleshooting Common Errors
If you see a “Unable to locate package” message, double‑check the repository URL and the key import step. Verify that you’re connected to the internet and that the repository file exists in /etc/apt/sources.list.d/.
A frequent issue is DNS leaks. Run dig @8.8.8.8 aaaa.me after connecting. If you still see your real IP, configure the client to use DNS over TLS.
For packet loss or high latency, try switching to the Secure Core server or disable the built‑in kill‑switch temporarily to isolate the problem.
When experiencing “connection timed out,” the Sudo apt install proton vpn-gnome-desktop article suggests disabling IPv6 or changing DNS servers.
Remember to check ProtonVPN’s official status page for maintenance notices that could affect connectivity.
Uninstalling the ProtonVPN Client
If you need to remove the client, run:
sudo apt purge protonvpn-gnome-desktop
Followed by:
sudo rm -rf /etc/protonvpn
This command cleans all configuration files, ensuring a clean slate for a fresh reinstall.
To delete the repository, simply remove the protonvpn.list file:
sudo rm /etc/apt/sources.list.d/protonvpn.list
Refresh the package list again to confirm removal:
sudo apt update
With these steps, you’ll have fully uninstalled ProtonVPN from your system.
Optimizing Performance for Streaming
When using ProtonVPN to access streaming services like Netflix or Disney+, latency matters. Select the nearest server with the “Fastest” option in the client.
Use the QoS feature to prioritize streaming traffic if your distribution supports it. This reduces buffering and improves playback quality.
For 4K streaming, connect to a high‑bandwidth server in the U.S. or EU. ProtonVPN’s Secure Core is not ideal for streaming due to extra hops that add latency.
Enable the Kill Switch to prevent DNS leaks if your ISP might throttle VPN traffic. This feature is found in the client’s Settings panel.
Finally, consider using the ProtonVPN CLI on a Raspberry Pi or other low‑power device to keep a dedicated streaming node.
Setting Up Split Tunneling
Split tunneling allows you to direct certain apps through the VPN while others use your regular connection. In the GNOME client, click “Settings” then “Split Tunneling.”
Here, you can add applications or entire IP ranges. This is handy for accessing local network resources while still protecting your browsing activity.
For example, a local office printer can use the direct connection, while your browser stays encrypted.
ProtonVPN’s CLI also supports split tunneling via the --exclude flag. Add the application binary path to exclude it from the VPN.
Be cautious: misconfiguration can expose traffic, so double‑check the excluded list after setup.
Using ProtonVPN on Headless Servers
ProtonVPN’s CLI is ideal for headless servers that require secure outbound connections, such as web scrapers or Docker containers.
First, install the CLI:
sudo apt install protonvpn-cli
Authenticate:
protonvpn-cli login
Then connect:
protonvpn-cli c --securecore
After the VPN is running, you can start your services normally. All traffic will be encrypted.
Use systemctl enable protonvpn-cli@client to auto‑start the VPN on boot.
Monitor logs with journalctl -u protonvpn-cli@client for any connection issues.
Advanced Configuration: Using Custom Ports
ProtonVPN allows custom TCP and UDP ports to bypass restrictive firewalls. In the GNOME client, navigate to “Advanced Settings” and specify the port under the “Custom Port” field.
For UDP, default is 1194. If you’re blocked, try 443 or 1198. The CLI accepts the same parameters: protonvpn-cli c --port 1198.
Keep in mind that some networks block outbound VPN traffic; custom ports can circumvent this.
Test connectivity by pinging the server’s IP on the chosen port. A successful response indicates that the port is open.
Remember to adjust firewall rules on your server if you’re using a custom port that isn’t allowed by default.
Securing Your Connection with Kill Switches
ProtonVPN’s kill switch stops all traffic if the VPN disconnects. In GNOME, enable it via the “Security” tab. This protects against accidental data leaks.
The CLI offers --kill-switch when connecting. For example: protonvpn-cli c --kill-switch.
Test the kill switch by disabling your network interface with sudo ifconfig eth0 down while connected to the VPN. Traffic should cease immediately.
If you experience a false disconnect, check your routing table to ensure routes are properly set.
Always pair the kill switch with DNS over TLS to avoid DNS leaks.
Integrating ProtonVPN with Firewall Rules
If you use ufw or iptables, allow VPN traffic on the selected port. For example, to allow TCP 1194:
sudo ufw allow 1194/tcp
To block all other outbound traffic, add a rule to drop packets that are not part of the VPN interface:
sudo iptables -A OUTPUT -o vpn0 -j ACCEPT
sudo iptables -A OUTPUT -j DROP
Replace vpn0 with the actual interface name, which you can find using ip addr.
These firewall settings give an extra layer of protection against DNS leaks and IP exposure.
Remember to save your rules to persist across reboots, e.g., sudo iptables-save | sudo tee /etc/iptables/rules.v4.
Keeping ProtonVPN Updated
Regular updates ensure you receive the latest security patches. Run:
sudo apt update && sudo apt upgrade -y
ProtonVPN also releases a dedicated update script for the CLI:
protonvpn-cli update
Check the client’s “About” section for the current version number.
ProtonVPN’s repository is configured to auto‑update, so you won’t need to manually add new keys.
Stay informed by subscribing to ProtonVPN’s blog for announcements about new features and bug fixes.
Configuring ProtonVPN for Workstations
For enterprise users, ProtonVPN can be integrated into corporate policy. Use the Secure Core feature to route traffic through multiple hops, ensuring compliance with GDPR or CCPA.
Configure group policies in your Linux distribution’s configuration management system (e.g., Ansible) to enforce VPN usage.
Set up a systemd service to automatically reconnect if the VPN disconnects due to network changes.
Use ProtonVPN’s “Force DNS” option to prevent DNS leaks, especially in corporate environments where sensitive data might be exposed.
Monitor VPN health via the systemd‑monitor or Prometheus exporters for uptime and latency metrics.
Accessing Restricted Content in the U.K.
UK users often need to bypass the UK’s “Internet Watch Tower.” ProtonVPN’s U.K. servers provide reliable access to UK‑only services like BBC iPlayer.
Use the client’s “Location” selector to pick the nearest U.K. server. The “Fastest” button often chooses the optimal one.
When streaming BBC iPlayer, consider disabling the “Stealth” mode, as it may trigger additional verification steps.
Test playback by opening the BBC iPlayer website in a private browser session.
Remember to clear your cache between tests to avoid cross‑country IP detection.
Handling Proxy Settings on Linux
If your environment requires a proxy, configure ProtonVPN to use it. In GNOME, navigate to “Network” → “Proxy” and input your proxy details.
The CLI accepts proxy parameters: protonvpn-cli c --proxy http://proxy:port.
Ensure that the proxy does not bypass the VPN by confirming that all traffic routes through the VPN interface.
Use traceroute -I google.com to see the path. The first hop should be the VPN gateway.
For advanced users, combine the proxy with iptables NAT rules to enforce strict routing.
Using ProtonVPN with Docker Containers
To isolate container traffic through ProtonVPN, you can run the container with the VPN’s network namespace.
First, install the ProtonVPN client on the host. Then, use Docker’s --network=container: flag to share the VPN namespace.
Alternatively, use docker run --cap-add=NET_ADMIN with the VPN client installed inside the container.
Configure docker-compose.yml to specify the network mode:
network_mode: "service:protonvpn"
Test connectivity inside the container with curl https://api.ipify.org to verify the VPN IP.
Using ProtonVPN on Raspberry Pi
For Raspberry Pi users, install the CLI for lightweight usage:
sudo apt install protonvpn-cli
Authenticate and connect:
protonvpn-cli login
protonvpn-cli c
Set the service to start at boot:
sudo systemctl enable protonvpn-cli@client
Test the VPN by visiting whatismyipaddress.com.
Use the PiVPN script in tandem for a full VPN solution if you prefer an OpenVPN or WireGuard setup.
Optimizing for Low‑Latency Gaming
Gamers can benefit from ProtonVPN’s low‑latency servers. Select a server near your gaming region, e.g., a U.S. server for North American games.
Enable the Stealth mode to reduce packet inspection that can increase latency.
Use TCP 443 if you’re behind strict corporate firewalls.
Test ping times with ping -c 5 vpn-server-ip and compare them to your ISP’s public IP ping.
Adjust the client’s QoS settings to prioritize gaming traffic.
Securing Your Home Network with ProtonVPN
To protect an entire home network, install ProtonVPN on a dedicated device such as a Raspberry Pi or a small NAS.
Configure the device as a DHCP server, so all client devices automatically use the VPN gateway.
Set the network’s default route to the VPN interface via iptables and DHCP settings.
For additional security, enable the Secure Core option to route all traffic through ProtonVPN’s core network.
Monitor traffic with tools like ntopng or Grafana to detect any anomalous connections.
Managing Multiple VPN Accounts
If you manage several ProtonVPN subscriptions, you can create separate configuration files for each account.
Store credentials in ~/.config/protonvpn/accounts.json. The client automatically detects them.
Switch between accounts using protonvpn-cli switch --account account_name.
Use systemd units to run each account as a separate service.
Automate failover by scripting protonvpn-cli c --failover for seamless connectivity.
Monitoring VPN Usage with Logs
ProtonVPN logs are stored in /var/log/protonvpn-client.log. Review these logs for connection errors and troubleshooting.
Use journalctl -u protonvpn-client to view real‑time logs.
Configure log rotation with logrotate to prevent disk space exhaustion.
Set log levels to debug for detailed diagnostics, but remember to switch back to info once resolved.
Integrate logs with SIEM solutions like Splunk or Elastic Stack for enterprise monitoring.
Backing Up Your ProtonVPN Configuration
Export your settings with:
protonvpn-cli config export --file ~/protonvpn-backup.json
Store the backup in a secure location, such as a password‑protected archive or a cloud storage service with encryption.
Restore using:
protonvpn-cli config import --file ~/protonvpn-backup.json
This is especially useful when migrating to a new machine or after a system reinstall.
Automate backups using cron to run the export command nightly.
Keep a versioned history by appending the date to the filename.
Using ProtonVPN with Tor for Extra Anonymity
Combine ProtonVPN with Tor for double encryption. Connect to ProtonVPN first, then launch Tor Browser.
Configure Tor to use a SOCKS proxy at 127.0.0.1:9050 if you want to route all traffic through VPN+Tor.
For advanced users, set up a Privoxy proxy to filter web traffic and further obfuscate the Tor exit node.
Use iptables to redirect all web traffic to Tor:
sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-ports 9050
Be aware of the increased latency and potential legal implications when routing traffic through Tor.
Configuring ProtonVPN for Mobile Devices via Desktop Bridge
Some Linux desktops allow you to control ProtonVPN on Android through the ProtonVPN Desktop Bridge.
Enable the Bridge feature in the client’s settings. The desktop will then share its VPN tunnel with the Android device over Wi‑Fi.
Install the ProtonVPN mobile app on the device and select the “Use Desktop Bridge” option.
All traffic from the Android device will flow through the Linux host’s VPN connection.
This is useful for keeping your mobile data secure without an additional subscription.
Customizing ProtonVPN with Scripts
Create a Bash script to automate daily reconnections:
#!/bin/bash
protonvpn-cli disconnect
sleep 30
protonvpn-cli connect --fastest
Make the script executable:
chmod +x ~/vpn_reconnect.sh
Add it to cron for daily execution:
crontab -e then add: 0 3 * ~/vpn_reconnect.sh
This keeps your VPN fresh and reduces the risk of credential expiration.
Log the script’s output to a file for auditing.
Using ProtonVPN in Virtual Environments
When running virtual machines (VMs), ensure the host’s VPN is active before starting the VM.
Configure the VM to use the host’s network adapter in bridged mode so that all traffic passes through the VPN.
Alternatively, set up a host‑only network and route VM traffic through the VPN interface using iptables NAT rules.
For KVM/QEMU, add the following to the VM’s XML config:
<interface type='bridge'><source bridge='br0'></source><mac address='52:54:00:xx:xx:xx'></mac></interface>
Test connectivity inside the VM with curl https://ipinfo.io/ip to confirm VPN usage.
Handling IPv6 Traffic with ProtonVPN
ProtonVPN supports IPv6, but some users disable it to avoid leaks. In the client settings, toggle “IPv6” off.
On the CLI, use protonvpn-cli c --no-ipv6 to enforce IPv4-only traffic.
Verify no IPv6 leaks by running curl https://api64.ipify.org after connecting. If you still see an IPv6 address, double‑check your system’s IPv6 configuration.
Use sysctl to disable IPv6 globally if necessary:
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
Remember to re‑enable IPv6 when you no longer need the restriction.
Using ProtonVPN in a Multi‑User System
On a system with multiple user accounts, you can set the VPN to run as a system service.
Create a systemd unit file /etc/systemd/system/protonvpn.service with:
[Unit]
Name=protonvpn.service
After=network-online.target
[Service]
User=root
ExecStart=/usr/bin/protonvpn-cli c --securecore
Restart=on-failure
[Install]
WantedBy=multi-user.target
Enable and start the service:
sudo systemctl enable protonvpn.service
sudo systemctl start protonvpn.service
All users will then benefit from the VPN connection without individual configuration.
Use systemctl status protonvpn.service to monitor the VPN health.
For per‑user VPN, install the client in each user’s home directory and manage connections independently.
Integrating ProtonVPN with DNS Leak Protection Tools
Install DNS leak protection utilities such as dnscrypt-proxy:
sudo apt install dnscrypt-proxy
Configure ProtonVPN to use dnscrypt-proxy by editing /etc/protonvpn/config.ini:
dns_server=127.0.0.1:5300
Restart the VPN client and verify DNS requests are routed through the proxy:
dig @127.0.0.1 aaaa.me
This ensures no DNS leaks occur even if the VPN disconnects abruptly.
Using ProtonVPN for Secure File Transfers
For SFTP or SCP transfers, route traffic through the VPN to protect sensitive data.
Use the Secure Core mode to add an extra layer of anonymity.
Test the connection by transferring a small file:
sftp user@vpn-server:/home/user/
Confirm encryption by checking the encryption state in Wireshark.
For automation, include the VPN start/stop commands in your rsync or scp scripts.
Managing VPN Connections in Kubernetes
Deploy a sidecar container with ProtonVPN to secure pod traffic.
Add the protonvpn-cli container to your pod spec:
containers:
- name: vpn-sidecar
image: protonvpn/cli:latest
command: ["/usr/bin/protonvpn-cli", "c", "--fastest"]
Use iptables to redirect traffic from your main container to the VPN sidecar.
Ensure that the sidecar runs in the same namespace for proper routing.
Monitor pod logs for any disconnection events.
When scaling, set the sidecar as a DaemonSet to provide VPN access across the cluster.
Optimizing ProtonVPN for Low‑Bandwidth Connections
Switch to the Lightweight mode in the GNOME client for reduced data usage.
Use TCP 443 to avoid throttling on metered connections.
Enable the Kill Switch to prevent data leakage if the connection drops.
Monitor data usage via vnstat or nload.
Adjust the DNS over TLS setting to reduce DNS query overhead.
Using ProtonVPN for Secure Remote Desktop Sessions
When accessing a remote desktop over RDP or VNC, route the traffic through ProtonVPN to avoid eavesdropping.
Connect to a server in the same country as the remote host for lower latency.
Configure the VPN to allow the RDP port (3389) if the remote host requires it.
Test the connection with rdesktop -u user -p pass -g 1024x768 vpn-server-ip.
Verify that the session remains encrypted by checking the network traffic in Wireshark.
Using ProtonVPN in a Home Lab Environment
Set up a home lab with a Raspberry Pi running ProtonVPN to act as a VPN gateway for your network.
Install PiHole and configure it to use the VPN’s DNS to block malicious domains.
Use OpenWrt routers to route all traffic through the Raspberry Pi.
Monitor performance with NetData dashboards.
For failover, configure a second Raspberry Pi with a redundant VPN connection.
Using ProtonVPN on Windows Subsystem for Linux (WSL)
WSL users can install ProtonVPN in the Linux subsystem and route Windows traffic through the VPN.
Install the client inside WSL and enable the “Allow Windows Apps” setting in the WSL config.
Launch the VPN from WSL and then open Windows applications; they’ll inherit the VPN connection.
Test with curl https://api.ipify.org in both WSL and PowerShell to confirm IP consistency.
Note that some Windows services may not respect the VPN if they run outside WSL.
