It looks like it might be a sr.ht issue? there's no errors, the sizes of builds look alright, and the build script completes its run. It's weird that only uxn has that issue like you said, I just resubmitted bicycle:

https://builds.sr.ht/~rabbits/job/1001867

And it now fails after failing to grab the uxncli for the first time, that didn't happen 4 days ago when I last made a commit. So it's something that happened recently

Aha, that's great that you found out that it was still working recently!

The build of Uxn from three days ago was able to download the previous binaries (https://builds.sr.ht/~rabbits/job/1000033#task-upload) but my solar build system didn't get triggered, so after that job completed the “needs-solar-build” flag file was 404ing (presumably along with everything else now). So it was definitely working before that build and definitely not working afterwards.

It really seems like a recent Sourcehut problem then.

I just retried the job again and pages.sr.ht still aren't hosting the files

As you know, I've been working on a project that'll provide hosting for Merveilles folk, so you're more than welcome to be an early adopter for that and I can host the Uxn builds there before the rest of it is ready

Whether you prefer that or hosting with Microsoft or whatever, it'll be a pain to update all the references to — scratch that, I see you've already had to do that!
