lyx is asking for some adding packages, but I don't see what rpm might contain them: Warning: Document class not available ---------------------------------------- The selected document class Article (Standard Class) requires external files that are not available. The document class can still be used, but the document cannot be compiled until the following prerequisites are installed: article.cls Book (Standard Class) book.cls KOMA-Script Book scrbook.cls fancyhdr.sty enumitem.sty Also notes that I didn't install: latex pplatex platex latex2e' but have no idea which I would need or want (though I see packages with those names, no idea which I would want). Any idea how to find these packages amongst the repo rpms? Thanks!
