# Problems: Miede's ClassicThesis.lyx using Mageia 6

```Dear all,
I am now using Mageia 6, Kernel 4.9.35-desktop-1.mga6 / 64-bit / KDE```
```
```
My many LyX documents of various classes produced in Mageia 5 generated PDF without any problems. In Mageia 6 all other document classes do so as before but my "ClassicThesis.lyx" documents throw out error messages. I then tried Miede's original forms (nothing was added, edited or changed) and again no PDF was generated instead the following errors were reported:
```
classicthesis-LyX-v4.1
Latex Error: \bflabel undefined

classicthesis-LyX-v4.2_biblatex_biber

classicthesis-LyX-v4.2_biblatex_bibtex8

What could be the problem here?

Thanks and regards,
Michael
