Hello,

To signal that the blackmagic-io module does not load with kernel 4.20-rcX and 4.20
The modules seem to compile, but impossible to load blacmagic-io

Regards,
Jerome

I have the same problem in Kernel v4.20.6.
I tried the following command but "depmod" failed.

Code: Select all
$ sudo dkms install blackmagic-io/10.11.4a9 -k 4.20.6-042006-generic --verbose --force

The depmod says:

Could anyone help me?
