In principal it is the same in Ubuntu 12.04 as in Win7:
- Unzip the font files from the downloaded archive.
- Select the single font or multiple fonts for installation in the file manager.
- Right click the selection and choose "Open with Font Viewer" (I am not sure about the exact wording, but in German it is called "Mit Font Viewer öffnen").
- The Font Viewer shows the font and provides a "Install Font" button.
- Clicking the "Install Font" button installs the Font.
btw. I am using the Source Code Pro now happily in Qt Creator 2.5. Thanks a lot!
