Unsatisfiable requirements detected for package cuDNN

[vonpetersenn]

Hello,

when trying to add FluxPrune to my project that includes Flux, CUDA and cuDNN, there are version conficts that cannot be resolved.

I removed the packages Flux, CUDA, and cuDNN to first add FluxPrune and let it choose the Flux and CUDA version that it supports. But then I have a Unsatifiable requirements when trying to add cuDNN:

Original error message:

Yes this project has seen no updates while Flux and CUDA have had many. The existing Project.toml probably needs up to date compatibility bounds. Or ideally, the package should be updated to the latest Flux.
