Answer 1

Use Ubuntu 18.04 x86 (linux-64) and the environment.yml provided will work.

It fails on MacOS (M1 Silicon).

As has been pointed out in the other reply; exported environment files with explicit build numbers, and as it turns out fixed package version combinations; may not work if this host platform is different.

Exported environments are a great way to get reproducible environments, but the build platform must be the same. I suggest using conda info on the origin host and on the target host to check if they are the same.
