Hi I'm trying to build a Docker image on an Ubuntu virtual machine. During the execution of RUN conda env update -f /tmp/environment.yml && conda clean --all -y I've encountered failure. The error message is pasted in below:

Collecting package metadata (repodata.json): ...working... done
Solving environment: ...working... failed

I've managed to solve this issue. This is because some old version of packages can't be found if the free channel is not used. This can be solved by execute conda config --set restore_free_channel true before install the conda env.
