If you have a Debian based system, you most likely have the Synaptic Package Manager.
In the quick filter type in: fluid-soundfont-gm If you get no results add repository of: debian wheeze. main contrib non-free
Check that box after you have file located, and click apply.
This will install the sound fonts to be used system wide.
The sound fonts will be located in /user/share/sounds/fs2
open the LMMS setup and in the file paths for Default sound font file add
/usr/share/sounds/sf2/FluidR3_GM.sf2

Thank you this seems to work the same on openSUSE.

LMMS did not complain anymore when I imported a midi file, about not having set a sound font.

( for others on openSUSE replace synaptic in the above story, with yast, and prob packman repo for debian weeze)

I did not have to add any repository, but my openSUSE install is not very standard anymore.

You can test your install, with this.
