Package: libguestfs Version: 1:1.34.3-6 Severity: serious Justification: fails to build from source (but built successfully in the past)
libguestfs build-depends on linux-image-versatile which is no longer built from source and will be removed from unstable and testing. Once that is done this package will FTBFS. Please update the build-depends to remove linux-image-versatile so this does not happen.
