Docker build issue with conda

[Bloster]

Hello, when i'm trying to run

docker build - < Dockerfile

on your dockerfile, it runs perfectly until step [9/18] concerning conda.
The error message is the following :
condaerror.txt

And i can't find anything on the web except one link to stack overflow which didn't fix my problem.
FYI : I'm running on a windows with WSL on Ubuntu
