It’s an old post, but very effective and still useful.
Basically, enable the universe repository from within Ubuntu(refer to forums if you need help with this).
Run the below:
sudo apt-get install msttcorefonts
This should allow you to install that package. At the end of this, it looks like it clears the font cache for you, it does not, or doesn’t do this correctly – so, you must run the below:
sudo fc-cache -fv
And your done! Yay – pretty fonts!
If it doesn’t make sense, or you have issues pulling this also refer to the link I’ve provided above. There are many blogs, within that thread, that will provide you with more data on how to go about doing this.
