To install fonts for all users
for example the boring company font:
https://www.futurafree.com/wp-content/uploads/2017/04/futura-bold.zip
one need to login as root and create a directory under
/usr/share/fonts/
# tested on hostnamectl Static hostname: centos.localdomain Chassis: laptop Operating System: CentOS Linux 7 (Core) CPE OS Name: cpe:/o:centos:centos:7 Kernel: Linux 4.15.9 Architecture: x86-64 # in combination with:su - root; # become root # change into dir cd /usr/share/fonts/; # download font wget https://www.futurafree.com/wp-content/uploads/2017/04/futura-bold.zip # unpack unzip futura-bold.zip; # seems spaces in filename is no good mv "futura bold" "futura-bold"; # so one got now this new dir: ll /usr/share/fonts/futura-bold total 248K drwxr-xr-x. 2 root root 179 Dec 15 14:49 . drwxr-xr-x. 45 root root 4.0K Dec 15 14:49 .. -rwxr-xr-x. 1 root root 38K Aug 9 2015 Futura Bold.ttf -rwxr-xr-x. 1 root root 41K Aug 5 2015 Futura Extra Bold.ttf -rwxr-xr-x. 1 root root 49K Aug 5 2015 Futura Round Bold.ttf -rwxr-xr-x. 1 root root 28K Aug 5 2015 FuturaStd Bold.ttf -rwxr-xr-x. 1 root root 28K Aug 5 2015 Futura Std Extra Bold.ttf -rwxr-xr-x. 1 root root 49K Aug 5 2015 Futura URW Extra Bold.ttf # change permission rights # VERY IMPORTANT OR LibreOffice will not be able to access the font chmod -R ugo+rx futura-bold # or on the whole directory chmod -R ugo+rx /usr/share/fonts/ # now run this: # build font information cache files fc-cache -f /usr/share/fonts/
result should look like this:
