Comment 30 for bug 1457776

Unfortunalely I did this kind of upgrade in Debian, but I got two reports of broken updates (not due to a bad package, but an half configured virtualbox dkms state)
sorry but the fix will wait until Debian jessie is fixed (fix alredy done but we have been pointed to a better fix), and nobody spots regressions there.

Until now please use the ppa (that should be broken too, but I guess the problem is more prominent with newer dpkg versions)
