I installed Lyx in my system, but it I just can't make it work. Every time I open any file, I get a message similar to this one:
The selected document class article 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 See section 22.214.171.124 (Class Availability) of the User's Guide for more information.
I'm not sure if the problem is with Lyx itself or some of its Latex dependencies.
I do have the "article.cls" file in my system (from texlive-latex-base) located in:
(This line shows up in Tools → TeX Information, so apparently Lyx knows about it).
I have already tried reinstalling texlive and using Tools → Reconfigure, didn't work.
I'm using LyX 126.96.36.199 in KUbuntu 12.10.
EDIT: Apparently this is a bug in 12.10. I just reverted to 12.04 and everything is working smoothly again, with no setup needed beyond
apt-get install lyx.
