Hello. Both "ipywidgets" and "jupyter-notebook" build ok again, so I'm closing both bugs.
However, none of the packages had to change for this to happen. If somebody wants to reassign + affects based on the output of debbisect (which is the same for both packages), here it is: bisection finished successfully last bad timestamp: 20260522T083018Z first good timestamp: 20260522T203100Z the following packages differ between the last bad and first good timestamp: glycin-loaders 2.0.8-1 -> 2.1.2+ds-2 glycin-thumbnailers 2.0.8-1 -> 2.1.2+ds-2 jupyterlab 4.0.11+ds2+~cs11.25.27-1 -> 4.0.11+ds2+~cs11.25.27-3 libglycin-2-0:amd64 2.0.8-1 -> 2.1.2+ds-2 webpack 5.106.2+dfsg1+~cs15.15.23-2 -> 5.106.2+dfsg1+~cs15.15.23-3 Thanks.
