dkms no more compile module

[Le Gluon Du Net]

Hello,

each time there is a Ubuntu kernel update, some apps wich need a special kernel module does not start anymore (virtualbox, graphic drivers, cdemu...). I think dkms is broken on my system, please help!

$ dkms status
bbswitch, 0.7, 3.11.0-14-generic, x86_64: installedError! Could not locate dkms.conf file.
File: does not exist.
