The error I have not understood yet

[Yvour]

An error has occurred. This may have been caused by
an incorrect setting. The error is:
Could not find KVM version for this KVM binary, got version acceleration has been left in its default state. Got version -1

I am trying to build it from source but without success on latest Mint.

No one will be responding to the issues anymore this github project has died.
