2 years ago Manjaro user with the same issue. Thanks for mentioning the permission issues. I changed the permission of the jupyter directory to read and write allowed by anyone. It works, and the extensions can now be installed in jupyterlab.
Description
When I try to install an extension via the manager, I get
Error: 500 (Internal Server Error). When I Install it viasudo jupyter labextension install my-extension, it works without issues. Could it be that the permission are missing in Jupyter Lab? Tried starting it with root, but got a notificationt that it is not supposed to.Context
