There is a per-user font installation procedure, but we’ll do this system-wide just in case. This procedure presumes that you are using a modern fully-fledged Linux desktop which includes a font server.
- First we create a folder for manual font installs, and give it the right permissions.
sudo mkdir /usr/share/fonts/manual-installs
sudo chmod 0555 /usr/share/fonts/manual-installs - Copy all of your .ttf, .otf, etc., files, into the folder, and give them all the right permissions. We’ll say that you downloaded a file named Fonts.zip to Downloads in your home directory, and unpacked it.
sudo cp ~/Downloads/Fonts/* /usr/share/fonts/manual-installs
sudo chmod 0444 /usr/share/fonts/manual-installs/* - Update the font cache.
sudo fc-cache
