The missing package, jupyterhub-singleuser, is listed at https://anaconda.org/conda-forge/jupyterhub-singleuser but I could not find the feedstock recipe.

Can I have some help to know where this package is created? Thanks!

I think this is the problem. jupyter-resource-usage requires psutil<6 which isn't built for python 3.13

I think this is the problem. jupyter-resource-usage requires psutil < 6 which isn't built for Python 3.13

I contacted the developers of jupyter-resource-usage in jupyter-server/jupyter-resource-usage#251 asking for the requirements to be less restricted. A new release of jupyter-resource-usage was made https://github.com/jupyter-server/jupyter-resource-usage/releases/tag/v1.2.0. Now this new release need to be updated on conda-forge, see https://github.com/conda-forge/jupyter-resource-usage-feedstock.

@minrk can I have some help to understand why the test https://github.com/jupyterhub/repo2docker/blob/main/tests/venv/default/verify is failing here?

@minrk
fix venv/postBuild test
a39849b 
- switch to simpler jupyter-keepalive extension
- set -e in postBuild to catch errors
- set -x to see steps as they go for easier debugging

I think I fixed it. I believe it was the fact that jupyter-collaboration is no longer the name of the actual server extension package, it is now jupyter_server_ydoc. I switched it to a simpler extension that isn't going to have similar refactors, and added better output to both postBuild and verify to hopefully make it easier to see what's wrong
