The Sage tutorial says:
or from the Sage notebook (click Help, then click Tutorial to interactively work through the tutorial from within Sage).
but when I follow those directions I get: ``` 404 : Not Found
You are requesting a page that does not exist! ```
The url in the new tab that appears is:
http://localhost:8888/kernelspecs/sagemath/doc/tutorial/index.html?v=20210430004223
And the notebook server shows:
[W 08:24:19.246 NotebookApp] 404 GET /kernelspecs/sagemath/doc/tutorial/index.html?v=20210430004223 (127.0.0.1) 19.26ms referer=http://localhost:8888/notebooks/Untitled2.ipynb
What am I doing wrong?
```
