[Fontconfig] [fontconfig] proportional sans oxygen font not available

[Felix Miata]

What's the secret in any version of Fedora (e.g. 22) or openSUSE (e.g.
Tumbleweed) or *buntu (e.g. 14.10 or 15.04) to getting any "Oxygen"
(proportional regular sans, not mono, not bold) font to show up anyplace
except a KDE font configuration or installation panel or KDE's UI? I tried in
several versions of these three distros on multiple machines, and always
nothing from fc-match or anything else (helpful from) fontconfig. Trying to
get a locally installed (non-bold, non-mono sans, by whatever name; either
via package manager or placing the ttf files in /usr/local/share/fonts/)
Oxygen ttf font to show up on a web page styled to use Oxygen (sans) never
makes it happen, always falling back to some other font family.

e.g. Fedora 22:

# grep RETTY /etc/os-release
PRETTY_NAME="Fedora 22 (Twenty Two)"
# rpm -qa | grep xyge | grep ont | sort
oxygen-fonts-5.3.2-1.fc22.i686
oxygen-fonts-common-5.3.2-1.fc22.noarch
oxygen-mono-fonts-5.3.2-1.fc22.noarch
oxygen-sans-fonts-5.3.2-1.fc22.noarch
# fc-list | grep xyg
/usr/share/fonts/oxygen/Oxygen-Sans-Bold.ttf: Oxygen\-Sans:style=Sans-Bold
/usr/share/fonts/oxygen/Oxygen-Sans.ttf: Oxygen\-Sans:style=Sans-Book
/usr/share/fonts/oxygen/OxygenMono-Regular.ttf: Oxygen Mono:style=Regular
# fc-cat oxygen
/root/oxygen: No such file or directory
# fc-list oxygen
# fc-match oxygen
DroidSans.ttf: "Droid Sans" "Regular"
# fc-pattern oxygen
Pattern has 1 elts (size 16)
        family: "oxygen"(s)

# fc-query oxygen
Can't query face 0 of font file oxygen
# fc-scan oxygen
# fc-match -a oxygen | sort | grep xy
OxygenMono-Regular.ttf: "Oxygen Mono" "Regular"
Oxygen-Sans-Bold.ttf: "Oxygen-Sans" "Sans-Bold"
Oxygen-Sans.ttf: "Oxygen-Sans" "Sans-Book"
# fc-match "Oxygen Mono"
OxygenMono-Regular.ttf: "Oxygen Mono" "Regular"
# fc-match Oxygen
DejaVuSans.ttf: "DejaVu Sans" "Book"
# fc-match Oxygen-Sans
DejaVuSans.ttf: "DejaVu Sans" "Book"
# fc-match "Oxygen Sans"
DejaVuSans.ttf: "DejaVu Sans" "Book"
# fc-match "Oxygen Regular"
DejaVuSans.ttf: "DejaVu Sans" "Book"
# fc-match "Oxygen Sans Regular"
DejaVuSans.ttf: "DejaVu Sans" "Book"
