I am running Ubuntu 21.10 on a Lenovo Thinkpad X1 Tablet. I use Firefox 98.0.2 (64-bit) as by browser. When I run sage -n jupyter file.ipynb A new tab open is firefox with address file:///tmp/tmp9csp8qpp.html opens but Firefox reports
File not found
Firefox can’t find the file at /tmp/tmp9csp8qpp.html.
Check the file name for capitalization or other typing errors. Check to see if the file was moved, renamed or deleted.
However the file does exist. ls -l /tmp/tmp9csp8qpp.html returns
-rw------- 1 brett brett 751 Mar 25 10:15 /tmp/tmp9csp8qpp.html
When I run sage -n jupyter file.ipynb I get some links in the terminal toi use for opening the jupyter session in my browser:
To access the notebook, open this file in a browser: file:///home/brett/.local/share/jupyter/runtime/nbserver-101452-open.html Or copy and paste one of these URLs: http://hamm:8888/?token=cb4036e78faba0faa3bd0d50b73cc7a94e302196c474d878 or http://127.0.0.1:8888/?token=cb4036e78faba0faa3bd0d50b73cc7a94e302196c474d878
If I open the first of these, Firefox reports
Access to the file was denied
The file at /home/brett/.local/share/jupyter/runtime/nbserver-101452-open.html is not readable.
It may have been removed, moved, or file permissions may be preventing access.
However I have both read and write privileges for this file; ls -l /home/brett/.local/share/jupyter/runtime/nbserver-101452-open.html returns
-rw-rw-r-- 1 brett brett 667 Mar 25 10:15 /home/brett/.local/share/jupyter/runtime/nbserver-101452-open.html
I tried changing the privileges to include x but Firefox still will not open it.
