I am trying to build a docker image. This is the full dockerfile:
FROM ubuntu
ENV LANG=C.UTF-8 LC_ALL=C.UTF-8
ENV PATH /opt/conda/bin:$PATH
ENV TZ=Europe/Athens
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
RUN apt-get update --fix-missing && apt-get install -y wget bzip2 ca-certificates \
libglib2.0-0 libxext6 libsm6 libxrender1 \
git mercurial subversion
RUN wget --quiet https://repo.anaconda.com/miniconda/Miniconda2-4.5.11-Linux-x86_64.sh -O ~/miniconda.sh && \
/bin/bash ~/miniconda.sh -b -p /opt/conda && \
rm ~/miniconda.sh && \
ln -s /opt/conda/etc/profile.d/conda.sh /etc/profile.d/conda.sh && \
echo ". /opt/conda/etc/profile.d/conda.sh" >> ~/.bashrc && \
echo "conda activate base" >> ~/.bashrc
RUN apt-get install -y curl grep sed dpkg && \
TINI_VERSION=`curl https://github.com/krallin/tini/releases/latest | grep -o "/v.*\"" | sed 's:^..\(.*\).$:\1:'` && \
curl -L "https://github.com/krallin/tini/releases/download/v${TINI_VERSION}/tini_${TINI_VERSION}.deb" > tini.deb && \
dpkg -i tini.deb && \
rm tini.deb && \
apt-get clean
ENTRYPOINT [ "/usr/bin/tini", "--" ]
CMD [ "/bin/bash" ]
#SECOND PART
RUN apt install -y libgl1-mesa-glx
RUN conda install conda-build
RUN apt-get install -y git
WORKDIR /
RUN git clone https://github.com/cadquery/cadquery.git
WORKDIR /cadquery
RUN conda env create -n cq -f environment.yml
RUN echo "source activate cq" > ~/.bashrc
ENV PATH /opt/conda/envs/cq/bin:$PATH
WORKDIR /testing
However, when it is time to conda build - more specifically on STEP 12, this line here:
RUN conda install conda-build
i get errors.
It seems to be installing the packages normally, then it fails.:
Proceed ([y]/n)?

Downloading and Extracting Packages
UnicodeDecodeError('ascii', '/info/test/tests/data/\xed\x94\x84\xeb\xa1\x9c\xea\xb7\xb8\xeb\x9e\xa8.zip.json', 22, 23, 'ordinal not in range(128)')
The command '/bin/sh -c conda install conda-build' returned a non-zero code: 1
I replicated this error with the continuumio/miniconda2:4.5.11 Docker image:
$ docker run --rm -it continuumio/miniconda2:4.5.11 bash
(base) root@a285050719ad:/# conda install -y conda-build
# ... similar output as OP ...
UnicodeDecodeError('ascii', '/info/test/tests/data/\xed\x94\x84\xeb\xa1\x9c\xea\xb7\xb8\xeb\x9e\xa8.zip.json', 22, 23, 'ordinal not in range(128)')
Additionally, attempting to upgrade the conda package fails with some extra advice:
(base) root@a285050719ad:/# conda update conda
Solving environment: done
EncodingError: A unicode encoding or decoding error has occurred.
Python 2 is the interpreter under which conda is running in your base environment.
Replacing your base environment with one having Python 3 may help resolve this issue.
If you still have a need for Python 2 environments, consider using 'conda create'
and 'conda activate'. For example:
$ conda create -n py2 python=2
$ conda activate py2

That is, you really shouldn't be using these old Miniconda2 images because the conda is no longer compatible with the Anaconda Cloud repository.
A clean solution is to install a newer Miniconda (or Miniforge or Mambaforge). The latest ones all have Python 3 in the base. If for some reason one must have Python 2 in the base, which means you can't have the latest conda nor the latest conda-build, then it seems Miniconda up to 4.8.3 supported Python 2.
If possible, use the latest version, as in Python 3. One can always create a Python 2 environment if needed - just better that it not be in the base. Suggested solution:
RUN wget --quiet https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ~/miniconda.sh && \
...
Also, consider whether you can more simply start from an existing Docker image with Conda preinstalled.
A dirty version would be still using the same 4.5.11 installer, but then upgrading immediately. In the Docker image I can get it to upgrade to 4.8 and keep Python 2.7, then conda-build will install at 3.18.11 (current as of May 2021 is 3.21.4).
This could similarly be done in the Dockerfile with something like
RUN conda install -y python=2.7 conda=4.8 && \
conda clean -qafy && \
conda install -y conda-build && \
conda clean -qafy
Note: I needed the first clean to get conda-build to install.
