Looks like the problem is the following:

The following packages have unmet dependencies:
 sbuild-build-depends-lyx-dummy : Depends: libboost-signals-dev but it is not installable or
                                           libboost-signals1.67-dev but it is not going to be installed

Liviu, do you know how to solve this for the PPA?
