I suspect you don't have the kernel headers for your running kernel installed.
Do you actually have the "linux-headers-4.3.0-040300rc4-lowlatency" package (or whatever package providing those headers in Ubuntu) installed on your system ? Could you give me the output of "sudo apt-config dump | grep Recommends" ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1503099 Title: acpi-call-dkms 1.1.0-2: acpi-call kernel module failed to build To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi-call/+bug/1503099/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
