刚刚更新Ubuntu到22.04，现在我不能打开木星笔记本

Question

当我尝试启动木星笔记本时，浏览器会启动并得到以下错误：

Access to the file was denied

The file at /home/benjamin/.local/share/jupyter/runtime/nbserver-11758-open.html is not readable.

It may have been removed, moved, or file permissions may be preventing access.

我试着跑

jupyter lab clean --all
pip3 install jupyterlab --force-reinstall

根据这里的建议：Jupyter Notebook: Access to the file was denied。命令运行，但我仍然获得对文件的访问被拒绝错误。另外，在reinstall命令上，它会发出以下内容：

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
spyder 4.2.5 requires pyqt5<5.13, which is not installed.

fermipy 1.0.1+5.g5a57 requires astropy<4, but you have astropy 4.2.1 which is incompatible.

这可能是问题的一部分，也可能不是问题。

Answer 1

更新:我现在可以通过使用打印到控制台的URL访问笔记本。(只需复制并粘贴到Firefox浏览器中即可)

我仍然想弄清楚如何用'jupyter笔记本‘命令打开它，就像它在更新之前的工作方式一样，但是现在这是一个有用的解决方法。

Answer 2

你试过设置

c.NotebookApp.use_redirect_file = False

在jupyter_notebook_configuration.py文件中？

如果你试过，你是否删除了行首的“#”？

我的Ubuntu22.04也有同样的问题，这个问题得到了解决。

Answer 3

我首先用: jupyter笔记本-生成-config创建了这个文件，然后按照您所说的取消注释并更改行c.NotebookApp.use_redirect_file。

现在起作用了！
