fonts-dejavu-core package is not missing from my system, I removed the font files that come with it as I use the fonts that ship with TeX Live. More cases could result in this and generating software essential in the booting process should be robust.
Please use as fallback when the files from fonts-dejavu-core package are missing (this is already reported) $ fc-list |grep DejaVu|awk -F : '{print $1}' /usr/local/share/fonts/truetype/public/dejavu/DejaVuSans-Oblique.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSansCondensed-Oblique.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSerifCondensed-BoldItalic.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSansMono.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSansCondensed.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSerif-BoldItalic.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSerif-Italic.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSans-Bold.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSans-ExtraLight.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSerifCondensed-Bold.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSans.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSerifCondensed-Italic.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSansMono-Bold.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSansCondensed-Bold.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSerif.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSansCondensed-BoldOblique.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSansMono-Oblique.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSerifCondensed.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSerif-Bold.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSansMono-BoldOblique.ttf /usr/local/share/fonts/truetype/public/dejavu/DejaVuSans-BoldOblique.ttf -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1221264 Title: Missing font booting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1221264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
