Conda env configuration problem in sysbio-training/masters-2020/epigenetics/Dockerfile

[iromeo]

Due 'PATH="/opt/conda/envs/bio/bin:${PATH}"' >> ~/.profile & in the line

# Fix: R shell uses env variables from ~/profile
RUN echo 'PATH="/opt/conda/bin:${PATH}"' >> ~/.profile && \
	echo 'PATH="/opt/conda/envs/bio/bin:${PATH}"' >> ~/.profile && \
	echo 'LD_LIBRARY_PATH="/opt/conda/lib:${LD_LIBRARY_PATH}"' >> ~/.profile && \
	echo "export LC_ALL=C.UTF-8" >> ~/.profile && \
    echo "export LANG=C.UTF-8" >> ~/.profile

users get bio conda env bin folder even if the other environment is activated, this leads broken environments except bio:
