Overall, Linux support is an area that Proton really needs to prioritize.

https://magistvapk.cl/

They have Debian, Ubuntu, and Fedora apps. I am on Fedora and the app looks like some sketchy software from the late 2000's. Again, a little disturbing how they haven't prioritized this higher. It's as if the entire Proton team have been replaced with new people that are still being brought up to date on the business. OPEN THE LINUX APP! ITS A JOKE! For me, not even usable. In this day-and-age, they could probably have it vibe coded and fully shipped before it even hits lunch break. Give me a f***ing break Proton. Get your sh*t together or gtfo. If you guys aren't using AI to vibe code all the community suggestions before the year is done, or at the VERY latest by the end of 2027, the likelihood of renewing my sub will be quite low. Stop adding random **** to your project scope and focus on your core business.

*edit: Also a user of Fedora KDE. A user (Vao) mentioned it doesn't work in KDE, but I got it to "work" fairly quickly. I had an error during the last stage of installing (Fedora GNOME version) so had to do:
sudo systemctl enable me.proton.vpn.split_tunneling.service
sudo dnf reinstall proton-vpn-daemon
Then that got it to work. Although to be honest, as my comments above have expressed, it sort of looks like its broken, unfinished, or something else is wrong with the app. I don't think it was my "fix", but more so the underlying point of this thread.

Linux desktop market share reached 4.7% globally in 2025, Global market share increased from 2.8% in July 2022 to approximately 4.7% by 2025. The U.S. Digital Analytics Program reported 6% of federal website visitors running Linux as of August 2025. 3.4% of steam users use Linux according to the steam hardware survey January 2026

The current Linux GUI is difficult to use and very prone to errors and crashing. I sometimes have to hard restart my PC with the power button because ProtonVPN has crashed and even the System Monitor or software restart cannot kill the program. Please bring the features available on other platforms and standardize the app. I am on the verge of switching to a different program entirely because of the horrible Linux app UX.

Hi Proton team, can you please... PLEASE, provide a real update on this? Your Linux community has been extremely patient over the years. Please be honest and let us know what is actually happening. Thanks! :)

Generally the linux support is something that proton needs to take seriously.

I’d like to echo what other users have mentioned: the VPN app for Linux feels pretty bare-bones right now and is missing several features. Adding more functionality would make it much more valuable and enjoyable to use. I’m really looking forward to seeing improvements in future updates!

After using Proton VPN in Windows and Android for a while, I spun up a Fedora machine and I was shocked how much less functional the VPN application is. Options to start on boot, profiles, clear UI that matches the other GUI clients, etc. all missing? Hope to see improvements here soon.

stealth mode does not work in the linux desktop client :( had to bridge from my phone

Linux ubuntu based only? what about fedora? and what about KDE? current version doesn't work with KDE

Without an efficient Drive for Ubuntu desktop application that can selectively sync just specific folders I can not use the service

All i see is improvements for MAC users. I wonder when Linux and/or GrapheneOS users will receive any improvement...

Not much to add other than replicate the GUI and functionality from the Windows version. After all, Linux should be the preferred OS in regards of privacy and security :-). Keep up the good work, I love the Proton products!

The idea it's planned I hope the Proton Team improves Linux app because many users used it. And the team should bring us a Drive's app although better vpn app is better and I hope to comes in a short time

Feature parity needs to become a Proton priority. I'm getting tired of being treated as less important than Windoze users.
No way I'm renewing my Unlimited in 2026.

The Linux app needs Profiles (and both Windows *AND* Linux need their Profiles to support city in addition to country to achieve feature parity with Android).

Then there's Split Tunnelling...

Can we please have an update on this?

Just switched to Proton about 2hrs ago and oh boy do I regret it. No one to blame just myself for overlooking this part of the research but I never thought they leave Split Tunneling out for Linux of all the functions. Not that there are many functionalities, it is an astonishingly basic app. Kind of an insult for a paying customer or bait to reel us in.

If the main roadblock to bring linux into parity with Windows and Mac is due the the number of different distros etc... Can it be done as an appimage so that one version satisfies all requirements?

I could not agree more with Joao Molina.
