The JupyterHub app allows you to install extensions, such as jupyterlab-git.
When I select to install the extension and trigger a rebuild (required apparently), the rebuild fails, and suggests to run it manually with

Did you also remove the existing notebook containers? Changing just the memory limit does not change the memory limit of already created notebook containers. This is because re-creating container is "lossy" (as in the conda/pip packages that got installed have to be re-installed). Please see https://docs.cloudron.io/apps/jupyterhub/#notebook-memory-limit . You have to run
/app/code/remove_notebook_containers.py -

I increased the app memory usage in cloudron to 1G and also set
c.Spawner.mem_limit = '1G', then restarted both the app and the notebook 'server' from the control panel, but neither of those actions changed the outcome.Thoughts?
@infogulch OK, I tried this quickly now and it looks like 1GB is not enough for those webpack builds. I just put it to 4GB and that worked out. Maybe 2GB will suffice too...

I tried several different memory settings. In my use case 4G was the minimum needed for rebuilding.
