Como instalar o driver BlackMagic para o kernel Linux 4.2.0

Question

Eu estava tentando instalar o driver BlackMagic no mais recente Ubuntu 15.10 (64 bits), mas estava preso com mensagens de erro:

Setting up desktopvideo (10.5a17) ... Preparing new blackmagic driver
for 4.2.0-16-generic kernel... Adding to DKMS Building (failed)

Adding to DKMS Building (failed) Loading modules... Enabling systemd
services... DesktopVideoHelper Starting systemd services...
DesktopVideoHelper
********* Failed to build driver(s)

Possible causes:
1. Driver is incompatible with your kernel version
2. Kernel headers/gcc/make/etc. is not installed
3. Kernel header version does not match the running kernel (4.2.0-16-generic)

Existe alguma maneira de instalar no novo kernel do Linux?

Aqui está um pequeno procedimento para corrigir os drivers BlackMagic 10.5 para trabalhar em sistemas Debian de 64 bits com kernels 4.2.x:

1. Faça o download e descompacte os drivers. (Blackmagic_Desktop_Video_Linux_10.5.tar.gz)
2. sudo apt-get install git se já não estiver lá.
3. cd Blackmagic_Desktop_Video_Linux_10.5/deb/amd64
4. Corrigir o deb usando fakeroot e código do driver do Github :

    fakeroot sh -c '
      mkdir tmp;
      dpkg-deb -R desktopvideo_10.5a17_amd64.deb tmp;
      cd tmp/usr/src;
      git clone https://github.com/iperry/blackmagic;
      rm -rf blackmagic-10.5a17/ && mv blackmagic blackmagic-10.5a17/;
      git clone https://github.com/iperry/blackmagic-io;
      rm -rf blackmagic-io-10.5a17/ && mv blackmagic-io blackmagic-io-10.5a17/;
      cd ../../../;
      dpkg-deb -b tmp desktopvideo_10.5a17_amd64-patched.deb;
    '

5. sudo dpkg -i desktopvideo_10.5a17_amd64-patched.deb
6. Continue com o restante da instalação normalmente.
