It looks like you're running linux 3.11 but you're trying to build bbswitch against linux 3.12.0-031200-generic. Try removing 3.12.0-031200-generic and see if it helps.
By the way, I can't reproduce this issue in 14.04 with 3.12. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1250440 Title: bbswitch-dkms 0.7-2: bbswitch kernel module failed to build To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bbswitch/+bug/1250440/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
