fwts-efi-runtime-dkms depends on linux-headers-generic or linux-headers metapackages.
In your environment the kernel/header package is of version 3.8.0-16-generic while `uname -r` gives the version 3.8.0-030800-generic. This causes this error. The new version of fwts 0.26.08-0ubuntu1 and new kernel and its header packages of version 3.8.0-18 are available in raring already. I can install fwts-efi-runtime-dkms without any problem. I will close the bug since it seems to fixed now. Please re-open it if it does not work for you. ** Changed in: fwts (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1166106 Title: fwts-efi-runtime-dkms 0.26.07-0ubuntu1: fwts-efi-runtime-dkms kernel module failed to build To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fwts/+bug/1166106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
