mullvad-browser: fails to build due to broken symlinks

[mergemoveagree]

Nixpkgs version

• Unstable (25.05)

Describe the bug

Building a NixOS config after recently updating the flake.lock (on Feb. 10, 2025) from a previous update (on Feb. 3, 2025) results in the derivation mullvad-browser to fail due to broken symlinks. However, importing the current commit (b7cde80) in nix repl and building it with :b results in no errors and is able to launch successfully.

I put the mullvad-browser package in my home-manager packages rather than my system packages if that is relevant.

Steps to reproduce

1. Update flake.lock to commit b7cde80
2. Build NixOS config

Expected behaviour

mullvad-browser successfully builds

Screenshots

No response

Relevant log output

error: builder for '/nix/store/3c91q2n1235zg31h6pwa245f7ilkpsh9-mullvad-browser-14.0.4.drv' failed with exit code 1;
