That's a hell of a temporary solution, thank you!
However, Launchpad is most unclear to the rookie I am :
I clicked on "latest version", I selected my build, but the I have a long
list of .deb packages at the end.
I picked the last one since the name was the simplest.
But on install, I miss a few dependencies (which is normal), but also
textures, sound, etc.
The problem is, I can't see no ufoai-textures package for instance. I guess
the "common" might do it. Maybe.
I suppose I'll try the "data" package first. I'm sure I don't need them all
'debug, for instance).
