I have successfully built IceCat using the Guix preview source (guix

- When IceCat 68 is built from source on this foreign distro (without
using any software from Guix to do the build), the built IceCat 68
works. The "Unknown U2F Error" does not occur. This means that the
system is configured correctly to allow me to use my security token,
and IceCat is built correctly to use it.
- However, on the same foreign distro, when I install IceCat 68 from
Guix, it doesn't work. I get an "Unknown U2F Error".
- Reminder: Firefox also works on this foreign distro. The "Unknown U2F
Error" does not occur.
Great work. What dependencies did you have to provide on the non-Guix
system?

If anyone has any advice about how to determine what code is actually
emitting the "Unknown U2F Error", that would really help me narrow down
the possibilities quite a bit.
I don't know if this will be helpful, but as I understand webauthn,
browsers provide a new JavaScript API for interacting with security
tokens. I suspect that the error is being generated some code the browser
calls a JavaScript program it has loaded calls that API. The text may not
be in the IceCat source, but presented by the JavaScript program in
response to and error in its API call. I was thinking, but haven't had the
time, to set up my own webauthn-using app, so I can control the
JavaScript.
That's my best guess at least, but it could be wrong, so don't let me lead
you astray :)
Best,
