[DRBD-user] dkms error with Ubuntu 18 Bionic

[wkmail]

On a new U18.4 install from the PPA I am running into this error at the end

drbd:
Running module version sanity check.
/usr/sbin/dkms: line 784: find_module: command not found
modinfo: ERROR: missing module or filename.
  - Original module

Just last week I had a successful install on U18.4, but that was kernel 
4.15.0-54

I am not completely up on kernel internals but from what I can google 
the problem is with Ubuntu not the module.

Can I use an older or modified /usr/sbin/dkms (i.e. the one from the -54 
kernel) to complete the install?

or am I asking form problems doing that and I should wait for the fix.
