Today I had this same problem with a font with extension .TTF (uppercase). There was an error during install of the font (the same error message).
Renaming the font to .ttf solved the issue. I was then able to install the font properly. Might the solution be something else, and it was just a coincidence? Not sure. Can anyone else with the issue try this workaround? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1104237 Title: font install fails silently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-font-viewer/+bug/1104237/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
