I've set up a docker image from ubuntu:xenial and installed everything from scratch (https://github.com/nilqed/fricas_docker/blob/master/Dockerfile:latest). After having fixed the issue described further below (0MQ design change), it's working again without downgrading the jupyter-client. Therefore, if you want to fix it yourself, the following steps were necessary: 1. pip install -U jupyter-client (undoing the downgrade) 2. clear the sbcl cache for "pzmq": ????=to complete rm -r ~/.cache/common-lisp/sbcl-1.3.0-linux-x64/???/fricas_jupyter/quicklisp/dists/quicklisp/software/pzmq-20150608-git/ 3. cd ????/fricas_jupyter/quicklisp/dists/quicklisp/software 4. rm -r pzmq-20150608-git 5. git clone https://github.com/orivej/pzmq.git 6. mv pzmq pzmq-20150608-git #cheating ;) 7. cd ????/fricas_jupyter 8. ./install.sh #recompile kernel Otherwise I'll update the git repo as soon as the new version of "pzmq" is released on QL, then you could pull the changes via git. Kurt >>> from http://stackoverflow.com/questions/34093656/jupyter-and-common-lisp/37107166#37107166 This issue is caused by a change in the size of the message structure, zmq_msg_t, in 0MQ version 4.1.x to 64 bytes from a size of 32 bytes in version 4.0.x. The 0MQ interface library used by cl-jupyter is pzmq, and that library is stated to support 0MQ up to version 4.0. At the time of this writing, pzmq uses a 0MQ message size of 32 bytes. This leads to internal errors if 0MQ version 4.1.x is installed. There are two solutions here: Downgrade the 0MQ installation to version 4.0.x Fix the pzmq library by updating the definition of msg% in c-api.lisp from 32 to 64 bytes. Update - 9 May 2016 The pzmq library was updated to support 0MQ version 4.1.x, (preserving compatibility with older versions). The new version of pzmq is planned for release as part of the May 2016 Quicklisp release. ++++ Libs ++++ root@7f4cc5b5c08a:~# apt list python-zmq Listing...
