03:29 <tnks> I tried to upgrade dependencies with Niv, and I ran into https://github.com/input-output-hk/haskell.nix/issues/884, but I'm not sure what the work-around is. I just reverted my attempt to upgrade for now, but still trying to understand this more.

03:34 <tnks> my best read of this issue is that some bad artifacts got into a cache, and I guess I can just try to upgrade again in a week or so, and maybe the problem will have flushed through.

11:52 <michaelpj> tnks: did you hit that on master after https://github.com/input-output-hk/haskell.nix/pull/885 was merged?
