Hello, I am trying to install proton vpn following this guide: https://protonvpn.com/support/linux-vpn-debian-ubuntu .

Unfortunately, when I want to install the proton-vpn-gnome-desktop package, I am encountering this error:

sudo apt install proton-vpn-gnome-desktop
Solving dependencies... Error!   
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

Unsatisfied dependencies:
proton-vpn-gnome-desktop : Depends: proton-vpn-gtk-app but it is not going to be installed
Depends: python3-proton-vpn-api-core (>= 4.14.0) but it is not going to be install
ed
Depends: python3-proton-keyring-linux (>= 0.1.0) but it is not going to be install
ed
Depends: proton-vpn-daemon but it is not going to be installed
Error: Unable to satisfy dependencies. Reached two conflicting assignments:
  1. python3-proton-core:amd64=0.7.4 is selected for install because:
1. proton-vpn-gnome-desktop:amd64=0.10.1 is selected for install
2. proton-vpn-gnome-desktop:amd64=0.10.1 Depends python3-proton-vpn-api-core (>= 4.14.0)
[selected python3-proton-vpn-api-core:amd64=5.5.11 for install]
3. python3-proton-vpn-api-core:amd64=5.5.11 Depends python3-proton-core (>= 0.5.0)
[selected python3-proton-vpn-api-core:amd64=5.5.11]
For context, additional choices that could not be installed:
* In proton-vpn-gnome-desktop:amd64=0.10.1 Depends python3-proton-vpn-api-core (>= 4.14.0):

  2. python3-proton-core:amd64=0.7.4 Depends python3-importlib-metadata
but none of the choices are installable:
[no choices]

Is there any solution I can pursue here?

Quoting AI: This is a known breakage: your error bottoms out at python3-proton-core depending on python3-importlib-metadata, and that package was removed from Debian unstable in April 2026 and dropped from testing on April 11, 2026. Proton's repo still targets Debian stable, so on Debian Testing the chain is unsatisfiable until Proton drops that dependency.

Is there any obvious fix? Did anyone else encounter this issue? Or should I just wait for Proton to fix the .deb package?
