Looks like the dkms package was indeed deprecated in later releases. The last ubuntu release where I can find it is artful:

Thanks to Christian Ehrhardt (Closes: #884656) Aha, that leads us to the upstream issue: https://github.com/vmware/open-vm-tools/issues/217 And this particular comment: https://github.com/vmware/open-vm-tools/issues/217#issuecomment-352119641 """ is there any reason you are trying to build vmxnet driver on kernel 4.15? This driver is not supported for kernel version >= 3.3, see https://kb.vmware.com/s/article/1001805. """ That kb article says: "Note: VMXNET driver is only supported on kernels earlier than 3.3" I guess this means this bug should be closed as "wontfix". ** Bug watch added: github.com/vmware/open-vm-tools/issues #217 https://github.com/vmware/open-vm-tools/issues/217 ** No longer affects: linux-meta-hwe-edge (Ubuntu) ** Changed in: open-vm-tools (Ubuntu) Status: Incomplete => Won't Fix -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to open-vm-tools in Ubuntu. https://bugs.launchpad.net/bugs/1779793 Title: open VM tools DKMS fails to build mostly due to multiply defined preprocessor symbols [error: implicit declaration of function 'init_timer_deferrable'] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/open-vm-tools/+bug/1779793/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
