I suspect you're probably right about the removable-media interface. It
works for me on Debian without that interface connected, but that's
possibly a feature of the way confinement is implemented. Many of the
restrictions are only effective on Ubuntu.

If you think it would be useful to have the removable-media interface
added to Octave, please open an issue on the octave-snap project
(https://github.com/octave-snap/octave-snap/issues). It would be best if
you are able to demonstrate that it doesn't work as is, and does work if
you run in devmode.
