I have had trouble locating any specific help with what appears to be an installation problem.
I installed Jupyter Lab using the recommended method of pip install jupyter-lab from jupyter.org.
System Details:
- OS is Mint 20.3 Cinnamon
- Browser is Chrome (v 103.0.5060.114)
- Python is 3.8.10 (64bit)
After having issues when trying to open older notebook files I discovered I can’t even create a new file. All attempts respond with the following error:
Unexpected error while saving file: Downloads/Untitled.ipynb [Errno 2] No such file or directory: '/home/user/Notebooks/.~Untitled.ipynb' -> '/home/user/Notebooks/Untitled.ipynb'
A file of this name was created but opening the file in a text editor shows it to be empty. Nothing, not even initialization information, was written to it. I get the same error when I open an existing file from the same (or any other) directory.
I have tried the usual uninstalling and reinstalling as well as rebooting and cleaning out old preferences. Does anyone have an idea as to what may be wrong?
Additional Detail from running jupyter lab with the debugger after tapping the File → New → Notebook:
