@staticfloat Have you seen such errors before? https://buildkite.com/julialang/turingtutorials/builds/603#0186d07c-4c56-4563-8af2-236f4af088ec And do you know how to fix them? Could we maybe clean the cache?

I think the issue here is that the version of Rmath.jl being used is very old; you should update to 0.6 or 0.7, so that you get the JLL-compatible version.

Oh yes, you're absolutely right. I missed these downgrades, it's also an ancient version of Turing apparently.
