I have exactly the same symptoms - every time I create a new file (or even when I read documentation, via the help menu) LyX complains about the missing. I just installed LyX 2.0.5.1 from the Windows binary installer to WinXP. I don't think the problem is Ubuntu specific.

Texlive-xetex, etoolbox: use the XeTeX typesetting system Sgmltools-lite: export SGML DocBook documents Linuxdoc-tools: export SGML LinuxDoc documents Librsvg2-bin, inkscape: use the SVG image format in LyX documents (if your using Inkscape as your graphics editor inr Lyx) Groff: improved table formatting in plain text exports When i installed these, all my document classes became available.įor additional document classes (subclasses) and other how tos you can visit the Lyx Wiki hereĭvipost: display tracked changes in DVI format output Those that are NOT in bold are optional (i think they are self explanatory anyway). They are all available in the Ubuntu Software Center. If you only installed the Lyx Processor and Tex-live then you need to extend the functionality of LyX by installing the listed packages (in bold) for full functionality.

I just reverted to 12.04 and everything is working smoothly again, with no setup needed beyond apt-get install lyx. I have already tried reinstalling texlive and using Tools → Reconfigure, didn't work.ĮDIT: Apparently this is a bug in 12.10. (This line shows up in Tools → TeX Information, so apparently Lyx knows about it).

I do have the "article.cls" file in my system (from texlive-latex-base) located in: /usr/share/texlive/texmf-dist/tex/latex/base/article.cls

I'm not sure if the problem is with Lyx itself or some of its Latex dependencies. See section 3.1.2.2 (Class Availability) of the The document class can still be used, but theĭocument cannot be compiled until the following Requires external files that are not available. Every time I open any file, I get a message similar to this one: The selected document class I installed Lyx in my system, but it I just can't make it work.
