I've checked your document. On my system, there are all fonts missing, which is obvious because I didn't install your fonts.
Your warning reads: »The file maybe damaged or may have been produced in a later version of Scribus«
So check the versions you have used, and make sure the 1.5.7 is really installed. You can see it at the very top of the window, where the version number is displayed. If it is called 1.4.8 it is not the latest version.
Maybe you have a nightly build installed on your Linux machine?
