I am having the exact same issue with kernel 4.15.16 from the mainline kernel ppa sing make-kpkg.
However, 'make bindeb-pkg' will actually produce a fully functional header image. So I compared the two resulting packages and found 'tools/objtool/objtool' is missing in the make-kpkg package. Actually, there are a lot of files missing, but copying objtool to the correct place fixes DKMS builds for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752857 Title: 3rd party kernel modules fail to build due to incomplete /usr/src /linux-headers-4.1x.y install?
