Open your home folder in the file browser, and select View->Show Hidden Files. If you can’t find the .fonts folder, create it.
You can copy any TTF font file into this folder and it will become available immediately to applications after they are restarted. You can get TTF fonts from the Internet, or even a Windows system.
Installing Microsoft Truetype fonts on Ubuntu
You can install the MS core fonts by installing the msttcorefonts package. To do this, enable the “Universe” component of the repositories. This is done by default in Feisty. After you do that, use the following command from the command line:
$sudo apt-get install msttcorefonts
