Details:

Reproducible with Octave 4.4.1 on Manjaro 17.0 fresh install
Not reproducible on with Octave 4.2.2 on Ubuntu Server 18.04

Octave spews this string of errors semi-randomly


Unable to revert mtime: /usr/share/fonts/oiio
Unable to revert mtime: /usr/share/fonts/util
Unable to revert mtime: /usr/share/fonts/encodings/large
Unable to revert mtime: /usr/share/fonts/100dpi
Unable to revert mtime: /usr/share/fonts/75dpi
Unable to revert mtime: /usr/share/fonts/oiio


This does not affect the usability of the program from CLI but it seems to be
correlated with the file browser in the GUI being borked.

Workarounds:
- Run Octave as Root (also fixes the file browser issue)
- ignore the error and press enter for a fresh prompt

To me this looks like Octave is modifying font files and trying to hide that
it did??

I haven't tested 4.4.1 on a different distro, maybe this is all Manjaro's
fault but some documentation on this error would be nice.
