hm, I see speculos had a Traceback with IndexError: bytearray index out of range and I found what looks like a similar issue here LedgerHQ/speculos#488 (comment)

I tried with a different firmware version in #102 with no luck. We could possibly try a different device than the nano s.

I got this to build with ubuntu 20.04 and rust 1.63 but with stable rust fails due to an error about requiring glibc 2.33. I think the stable rust version does work with ubuntu 22.04. I suspect some dependency is updated with stable rust and we need to pin that. Interestingly nightly rust works fine with 20.04 (in the doc example test). I think when I tried with ubuntu 22.04 rust 1.63 and nightly failed.

@notmandatory I was researching this and the failure started to happen on version 0.8.4 further, the IndexError: bytearray index out of range error seems consistent on all versions from 0.8.4 up to 0.9.1.

In the PR #103 I was playing with the versions, it was only failing due to the glibc error on 1.78 (stable), but it works on previous ones, and in the nightly as you've mentioned (1.80).

It's weird, because I've tried to reproduce the failure on stable locally and wasn't able to, and now it worked on the CI 😅

Maybe it's related to the runner machine being used at the moment CI is running ?

Got it all working! updated description with details.
