https://gitlab.com/lilypond/lilypond/-/merge_requests/1980 > What is a 'variation font'? A font that contains one or more 'axes' like 'weight' or 'width' to modify its shape.

Apparently, somewhere in your score there is a glyph that isn't covered by LilyPond's default fonts or the fonts that you specify with `font-name`. For such glyphs, LilyPond relies on Fontconfig to find a fall-back font that contains it. Recently, it becomes more and more common in distributions to use Variation Fonts as fallbacks – you only need a single font to cover a bunch of font widths and weights! Alas, LilyPond doesn't support it for technical reasons. Werner
