[Solved] Update Fedora 27 to 4.15.3 breaks virtual box additions

[Duanehebert]

Using VirtualBox 5.2.6 r120293 on Windows 7 host with Fedora 27 guest. After update Fedora from 4.14 to 4.15 the VBox Additions fail. If I load the previous kernel everything works.

Trying to start the vboxadd service gives me the error that the module can't be loaded and suggests looking at /var/log/vboxadd-setup.log. If I try building the additions using VBoxGuestAdditions.run, it fails on the kernel module with the same suggestion.

vboxadd-setup.log contains:

Building the main Guest Additions module.
make V=1 CONFIG_MODULE_SIG= -C /lib/modules/4.15.3-300.fc27.i686/build SUBDIRS=/tmp/vbox.0 SRCROOT=/tmp/vbox.0 -j1 modules
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 have complete kernel sources etc. I've also tried the suggested make oldconfig and make prepare but this doesn't help. is there something else I can check?

After reading a post from Socratis below I installed the test version 5.2.7 r120865. When trying to launch my 4.15 kernel, it wouldn't mount the extensions for some reason but after launching the 4.14 kernel and installing the extensions I was able to boot with the 4.15 kernel and it works as expected.

I have about 14 Kposts, not sure which one you refer to...
But I'm glad you got it going. Marking as [Solved].
