Public bug reported: In Ubuntu 16.04.3 LTS, new install (well, as of a few months ago), italic/oblique variants just weren't installed by default. In some programs this resulted in text not showing, in others it resulted in those square boxes that indicate no font installed showing. The issue is in fonts-dejavu-extra which apparently doesn't exist in Ubuntu, so I've selected I don't know, even though I have a damn good idea.
The only way to fix this that I quickly found is to install the "transitional dummy package" that "can be safely removed" ttf-dejavu- extra. With this package installed, all the variants of DejaVu are installed. With it removed, the problem occurs. This package installs the extra font DejaVuSans-Oblique.ttf: "DejaVu Sans" "Oblique". I present the output of some commands to demonstrate the issue: me@mine:~$ apt-cache policy fonts-dejavu-extra fonts-dejavu-extra: Installed: 2.35-1 Candidate: 2.35-1 Version table: *** 2.35-1 500 500 http://au.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 500 http://au.archive.ubuntu.com/ubuntu xenial/main i386 Packages 100 /var/lib/dpkg/status me@mine:~$ fc-match -s sans-serif | grep -i dejavu DejaVuSans.ttf: "DejaVu Sans" "Book" DejaVuSans-Bold.ttf: "DejaVu Sans" "Bold" DejaVuSans-BoldOblique.ttf.dpkg-new: "DejaVu Sans" "Bold Oblique" DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book" DejaVuSerif.ttf: "DejaVu Serif" "Book" me@mine:~$ sudo apt-get install ttf-dejavu-extra Reading package lists...
