LyX 1.6.1 (Jaunty) russian support totally broken

[Dmitry Tantsur]

Binary package hint: lyx

Current LyX won't convert files containing Russian characters to PDF, DVI or anything else. Neither can it print anything.
Error message: LaTeX error: File 'koi8-r.def' not found.

Changing encoding to for example CP1251 won't help (similar error message), changing to uft8 causes lots of errors, forst of them being:
Error message: Package babel error: No Cyrillic encoding definitions files were found.

Your installation is incomplete.
You need at least one of the following files:
  x2enc.def, t2aenc.def, t2benc.def, t2cenc.def,
  lcyenc.def, lwnenc.def, ot2enc.def.

Installing anything containing "LaTeX" or "TeX" doesn't seem to help.
LyX 1.6.1-1, Ubuntu Jaunty alpha 1 (the problem occured in previous versions of LyX as well).
I can also mention that the same version of LyX works under Mandriva (2009) so it seems to be a package inconsistency rather than LyX error.

Have you tried installing package texlive-lang-cyrillic ?

[Dmitry Tantsur (divius)]

Of course, I've found this solution. But you know it's not obvious, I've been confused for about half a year. Is there a way to add this dependency when user's language is Russian? Or maybe we should make this package recommend for Lyx?

Is the situation better now?
