[Kernel-packages] [Bug 1292118] Re: virtualbox-dkms 4.1.12-dfsg-2ubuntu0.6: virtualbox kernel module failed to build [error: incompatible types when returning type ‘kuid_t’ but ‘RTUID’ was expected]

yes, that's because you don't have a pristine precise sources.list (ie no more than main, universe, multiverse, & restricted from precise, precise-updates, and precise-security; no ppas or backports). apt-get source virtualbox=4.1.12-dfsg-2ubuntu0.6 apt-get build-dep virtualbox=4.1.12-dfsg-2ubuntu

better late than never; didn't realize i would have to do everything myself. apt-get source virtualbox cd virtualbox-4.1.12-dfsg patch -p1 <../linux-3.13-virtualbox-host-kernel-modules.patch apt-get install build-dep virtualbox apt-get install devscripts fakeroot debuild -i -us -uc cd .. dpkg -i v
