shows the details of this error. It happens when invoking opera and opera-beta browsers.

I don't know if it is more widespread.

Those messages are effectively harmless. They occur because some apps are packaged with their own copy of libfontconfig.so.1 that's older than the FontConfig 2.13.0 version currently distributed with Fedora 28.

FontConfig 2.13.0 introduced some new features into its /etc/fonts/conf.d/ files that the older library doesn't recognize or know how to process. But there's nothing you can do about those messages (the only solution is for the apps that include an older libfontconfig.so.1 to either update their internal FontConfig, or stop including it entirely and just use the system /usr/lib64/libfontconfig.so.1), and they shouldn't have any impact on your being able to use the application(s).

Not sure I understand this but thanks. It's annoying.

Oh, I completely agree, it is annoying. What it boils down to is, it's opera's "fault" if it's anyone's fault (but also Firefox's, and Chrome's, and a bunch of other apps), since they need to update their included library to handle the new config files included with Fedora. But it's also a very rare situation, as the FontConfig file format almost never changes. Once they get caught up to 2.13.0 or newer, it'll be solved and isn't likely to come up again any time soon.

Thanks a lot for the clarification. I understand better now. And I am running opera-beta which is better than the stable one. I hope they will update the fonts sooner rather than later.
