Hi, I have a Metaflow+Conda question, asking here because you may have come across this too! We noticed that resolving environments for AWS Batch/linux-64 on macOS now throws an error "can't extract ncurses archive on case-insensitive file system". ncurses (dependency of Python) was recently updated to use a 
.conda
archive instead of the old 
.tar.bz2
. This reproduces the error for me: 
CONDA_SUBDIR=linux-64 conda create -n test python
, even with 
CONDA_SAFETY_CHECKS=disabled
, maybe the safety checks don't consider 
.conda
archives. 
CONDA_SAFETY_CHECKS=disabled CONDA_SUBDIR=linux-64 conda create -n test python ncurses=6.3
works, I haven't tried it yet in a 
@conda
decorator but I assume it will work there too. Out of curiosity, do you have / would you recommend case-sensitive file systems on Mac or do you use a separate APFS volume for the Conda packages directory as suggested here? https://github.com/conda/conda/issues/6514

I can look into this and provide a work around by early next week. Would that work?

yes, thank you!
We're currently adding ncurses 6.3 to @conda(dependencies=...) and this works, if you have a better idea this would be great 🙂
Hi, did you get a chance to look into this?
Hi, we're still working around this case insensitive file system error by pinning ncurses=6.3, bumping this thread in hope that someone knows a better solution 🙂

+1 to this thread! Hitting this with AWS Batch/linux-64 on macOS
Actually, updating to 
metaflow v2.11
fixed this ✅
