Hi, I found out about this problem when going on Rust's website at https://www.rust-lang.org/tools/install and they tell me that "It looks like I'm running Windows". I checked their code and they look for the navigator.platform value, which on IceCat on Guix System is "Win32". Obviously, Guix System is not Windows. Or is it? IceCat version: 68.6.0esr Cheers, Alexandru-Sergiu Marton https://brown.121407.xyz [8571 7664 DFDC 6B6A 3ED2 DA68 2348 7CC8 2397 2C1F]
