Describe your issue

I just deleted ~/.cache to clear up some disk space but now micromamba install errors because it is still trying to use the cache which no longer exists.

Can you try using micromamba clean --all instead so that it does the cleaning properly, and report if this solves the issue? Thanks!

That is what I did to get it working, but that's beside the point. The issue is that mamba is treating the cache as a persistent data store when they are specifically not meant to be treated that way. It should either be moved elsewhere if it has different mechanics, or mamba should treat the cache with the correct mechanics (i.e. the files can vanish at any time, especially when it isn't running).
