Komascript article

[Wolfgang Engelmann]

I can't find Koma-script-article under Documentclass, only 
Koma-script-Aufsatz (German version). I am using Debian and

LyX Version 2.2.0
I need the document class for a publication in a journal. It should also 
give a header line

(Benutzerdefinierte Kopf-/Fußzeilen, see 6.11 in User guide)
