Public bug reported:
Currently I am not able to build and sign Virtualbox drivers on the ubuntu with
snapped kernel (boot-managed-by-snapd).
The directory is read-only.
Maybe we should have this handled by building the dkms somewhere else,
but even if so, then how would I be able to sign them and insert?
I attached the Virtualbox log
..

This article suggest to build your own kernel and ship with these modules, but
for regular user seems like an overkill.
Is there an easier way ?
