New install failing on Ubuntu, Kernel mod

[Rikk]

I have a new install of kumbuntu (Umbuntu using KDE). The install works until is compiles and install the kernel mods.


I ran /sbin/vboxconfig, and /sbin/rcvboxdrv setup but still get "failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why." b
dmesg doesn't give any info but vbox-install.log in /var/log includes the following info:


make KBUILD_VERBOSE=1 SUBDIRS=/tmp/vbox.0 SRCROOT=/tmp/vbox.0 CONFIG_MODULE_SIG= -C /lib/modules/4.4.0-34-generic/build -j4 modules
make[1]: warning: -jN forced in submake: disabling jobserver mode.
test -e include/generated/autoconf.h -a -e include/config/auto.conf || ( \
echo >&2; \
echo >&2 " ERROR: Kernel configuration is invalid."; \
echo >&2 " include/generated/autoconf.h or include/config/auto.conf are missing.";\
echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it."; \
echo >&2 ; \
/bin/false)
mkdir -p /tmp/vbox.0/.tmp_versions ; rm -f /tmp/vbox.0/.tmp_versions/*
make -f ./scripts/Makefile.build obj=/tmp/vbox.0


I noticed the error Kernel configuration is invalid, I'm not versed in rebuilding kernels can some one help out on this?

What you noticed was "echo" code. If you post the complete install log ( as an attachment ) it might be more informative.

At would also help if you posted the exact version of the host and where you got your VirtualBox install.

Found out it has to do with the secure boot and the new kernel. I turned off secure boot on the computer re-installed the os and it works as it should now. Mod files need to be signed in order to be used
