If you run into this error repeatedly, your package cache may be corrupted.
Please try running `mamba clean -a` to remove this cache before retrying the operation.
Double-checking if the same issue exists with curl, I see

Looking at https://conda.anaconda.org/conda-forge/noarch/, I see that the channel is online, and while repodata.json and repodata.json.bz2 exist, the .zst variant doesn't.
Is this the rollout of a new feature and there's some temporarily inconsistent metadata? 🤔
