Bug Description

The sysdig-dkms module cannot be installed on the B-KVM kernel once before (bug 1764693), but now the installation works since 4.15.0-1007

However, when you try to insert the module, it will complain about:
$ sudo modprobe sysdig-probe
modprobe: ERROR: could not insert 'sysdig_probe': Unknown symbol in module, or unknown parameter (see dmesg)

Log in dmesg:
[ 1989.967807] sysdig_probe: loading out-of-tree module taints kernel.
[ 1989.967924] sysdig_probe: module verification failed: signature and/or required key missing - tainting kernel

This issue only happens on the KVM kernel, Bionic generic works fine with it.
