Hi, I had the same issue but I found a solution. I was creating a docker container based on ubuntu 20.04 and Python3.8.2. It installed openssl by default. The version from 2020-Mar-31 12:41:55 openssl-1.1.1f.tar.gz was giving me an this error: ssl.SSLError: [SSL: UNSUPPORTED_PROTOCOL] unsupported protocol (_ssl.c:1108). After looking for solutions, I found this link: https://cloudwafer.com/blog /installing-openssl-on-ubuntu-16-04-18-04/. In that link, you can find how to install openssl from the source. It shows you how to install the version from 2019-May-28 13:26:28 openssl-1.1.1c.tar.gz. First I built my container as originally and logged in and I followed the steps in the link. It solved my problem. The latest version from March 2020 was causing the issue.
I added the lines of code below when building the docker container to automate the steps. See: RUN apt install build-essential checkinstall zlib1g-dev -y WORKDIR /usr/local/src/ RUN wget https://www.openssl.org/source/openssl-1.1.1c.tar.gz && tar -xf openssl-1.1.1c.tar.gz WORKDIR openssl-1.1.1c RUN ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl shared zlib && make && make install COPY ./openssl-1.1.1c.conf /etc/ld.so.conf.d/ RUN ldconfig -v && mv /usr/bin/c_rehash /usr/bin/c_rehash.backup && mv /usr/bin/openssl /usr/bin/openssl.backup ENV PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/ssl/bin" * Note that I created the openssl-1.1.1c.conf file before building the container. The file is copied from the same directory where the dockerfile is saved. Create the file with that name and paste this inside: /usr/local/ssl/lib I hope this helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1888101 Title: 'unsupported protocol' error when using PyMySQL To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1888101/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
