@Phearret, it is a VBox bug whereby the VBox code did not support any linux kernel above 2.6.37. So it was triggered by upgrading your kernel to a version higher than your version of Ubuntu ships with, which was higher than older versions of VBox support. The bug is fixed in VBox 4.0.4 according to their web site. But you can also work around the bug by using the kernel version that Ubuntu came with.
It's really not a bug in Ubuntu at all, although sometimes we do release Ubuntu updates to avoid such conflicts between proprietary drivers (usually graphics) and new kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/769265 Title: package virtualbox-ose-guest-dkms 3.2.8-dfsg-2ubuntu1~lucid1 failed to install/upgrade: virtualbox-ose-guest kernel module failed to build (/build/include/iprt/types.h:...: error: linux/autoconf.h: No such file or directory) To manage notifications about this bug go to: https://bugs.launchpad.net/virtualbox/+bug/769265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
