Hi Yadd Jupyter notebook (python3-notebook) ships with symlinks in /usr/lib/python3/dist-packages/notebook/static/components to various javascript libraries which are served to the browser at runtime.
That autopkgtest checks for broken symlinks in that tree. Presumably the layout of dist files for marked has changed. I won't be able to look at this imminently, but there is a major version change of marked, there is probably API breakage as well. Since this only arises at runtime in the browser, it's not checked by autopkgtests. I'll look at this, but I'm not likely to be able to do so that quickly due to family commitments. Gordon
