How to install many font files quickly and easily?

Just create a .fonts folder in your home directory (if it doesn't exist) and unpack/copy them there.

It's also a good idea to manually rebuild the font cache, so you can immediately use the fonts everywhere:

fc-cache -f -v

Font Manager

Can manage multiple fonts easily with this application.

Can install mutiple fonts at a once.

To install new fonts click on "Manage Fonts" button as on the picture and click on "Install Fonts" in menu.

Can be installed with Software Center or with this command;

sudo apt-get install font-manager

Let's say your downloaded fonts are in fonts directory in your Downloads folder, Do these to install them

If you want the fonts to be usable by all users

Copy in /usr/share/fonts with command line

sudo cp -r ~/Downloads/fonts /usr/share/fonts/truetype/

Alternatively, Type this command in terminal to open graphical file manager if you prefer that way

sudo -i nautilus /usr/share/fonts/truetype

and copy the fonts from the downloaded directory to the newly opened folder in nautilus

If you don't bother for all users

In this case, the recommended way is to copy the fonts in ~/.local/share/fonts directory (It is not recommended to create .font directory directly under home anymore). When you put the fonts in that specified directory, Ubuntu will automatically start caching process. After 5-6 seconds, the fonts should appear in listing. Close any open application before you want to change the font for it.

Fixing the font files' permission bit

Font files should have the permission of 644 and the containing folder should have 755. So if you see don't see the fonts in listing, please check the permissions of those files and folders.
