This is a problem for the nfoview package which recommends and uses the xfonts-terminus fonts by default.
In fact I used to have these fonts in MATE Terminal too and everything was working perfectly in Bionic, but when I upgraded to Focal 20.04 yesterday I got empty squares all over the place. A screenshot is attached from Nfoview as well as the NFO file it was attempting to display. ** Attachment added: "Nfoviewer with a botched display with its default terminus fonts" https://bugs.launchpad.net/ubuntu/+source/xfonts-terminus/+bug/1870422/+attachment/5359673/+files/nfoview+xfonts-terminus.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870422 Title: Doesn't work on Focal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfonts-terminus/+bug/1870422/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
