Follow-up in case others have this issue.

One one of my computers this issue appears to have cleaned itself up. On the other I fixed it by installing fontconfig-ubuntu from the AUR.

The built-in file browser still has problems but I'll open a new report for that.

This is an upstream bug.  We don't need to leave the bug open because it can always be found by a search.

Agreed, this is a Fontconfig problem, not an Octave problem.

I can't reproduce this on my system even with the latest version, Fontconfig 2.13.1, that the Debian report refers to.

Looks like it due to a bug in recent versions of fontconfig:

http://debian.2.n7.nabble.com/Bug-909728-fontconfig-Spams-console-with-message-Unable-to-revert-mtime-usr-local-share-fonts-td4392956.html

I'll keep this report open for future references, but there is nothing Octave can do about it.

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.
