Hello. Was using the GNU/Debian/Linux package of Lyx for a long time without any problems. Recently, when opening old Lyx documents or trying to make a new one using a template, I consistently get error messages like the subject line above, "unknown text class".
As I use Lyx as a standard "production" app, this is annoying. Any pointers and/or advice much appreciated.
happens sometimes, when open an old doc. Often an old document class is not available after an update of teTeX. Could you show such a document or at least the beginning of the LyX doc?
