Hi all, The short symptom description is "Lyx 2.081 can't build PDF files if Document->Settings-Fonts->Use_non_tex_fonts is checked.
This happens on LyX 2.081 (Ubuntu LTS 14.04). Because this is a special Qemu host, upgrading the distro provided LyX would be an extreme hardship. Here's how to reproduce it with 2.081. I couldn't reproduce it on a (kind of broken) LyX 2.1.4 setup: Make a new LyX document. It defaults to the article document class, which is fine: This problem happens on the book document class too. Type in four or five words, save, and Ctrl+R. It produces a document, just like expected. Then, check Document->Settings->Fonts->Use_non_tex_fonts. Go back and Ctrl+R again, and this time it fails with the following error messages: =================================================================== Package fontenc Error: Encoding file `eu2enc.def' not found LaTeX error: Encoding scheme `EU2' unknown. LaTeX error: File `xunicode.sty' not found. =================================================================== Apparently this was fixed in later versions, but this VM guest is mission critical and I can't go messing with it. Could somebody please tell me what you did to overcome this issue in 2.081 (or similar)?
