Is it possible to recover jupyter notebook being deleted with a no permission error?

[HelloWorldLTY]

Hi all, I mistakely deleted my jupyter notebook, and I tried to look up it in the trash file. However, I met this error:
[Errno 13] Permission denied: b'/gpfs/gibbs/.Trash-19130'
Even if facing this error, jupyter still deleted this file.

I wonder if there are still methods or not to recover this notebook.

I tired to use the cache innner the browser, but the cache is not modified today and all content is wrong codes. Thanks.

Hi @HelloWorldLTY, thank you for submitting this issue. Generally you can look for a folder called .ipynb_checkpoints to look for older versions of your notebooks and recover them this way. If this doesn't work for you, you might have to rely on any backups you have saved.
