I've got a Macbook Air with Ubuntu installed, and I've had trouble in the past with my camera. I used patjak's solution from this forum thread, which I'll reiterate below.

sudo apt-get install git
sudo apt-get install curl xzcat cpio
git clone https://github.com/patjak/facetimehd-firmware.git
cd facetimehd-firmware
make
sudo make install
cd ..
sudo apt-get install kmod libssl-dev checkinstall
git clone https://github.com/patjak/bcwc_pcie.git
cd bcwc_pcie
make
sudo make install
sudo depmod
sudo modprobe -r bdc_pci
sudo modprobe facetimehd
sudo nano /etc/modules
**add line "facetimehd", write out (ctl+o) & close**

Now, this has worked for a while-- I've had to re-enter the code a few times after an update, but it worked afterwards. However, now it's officially not working anymore. I think the issue is after the sudo modprobe facetimehd step, where I'm getting this output: modprobe: ERROR: could not insert 'facetimehd': Exec format error

I'll be completely honest, I know practically nothing about coding (I know, "Then why are you using ubuntu," haha), so sorry if I sound like an utter newbie-- I am. Anyway, any idea what I ought to do next?

  • I think you'd better contact Patrik Jakobsson, who wrote the software you're building. You could do that by raising an issue. – Adriaan Oct 24 '20 at 08:11

I was getting the same "modprobe: ERROR: could not insert 'facetimehd': Exec format error" after upgrading. Making 'clean' before making facetime-firmware and bcwc_pcie fixed it for me. Although, you shouldn't have to do this if you are downloading a fresh copy of of the source code into an empty directory.

sudo apt-get install git
sudo apt-get install curl xzcat cpio
git clone https://github.com/patjak/facetimehd-firmware.git
cd facetimehd-firmware
make clean
make
sudo make install
cd ..
sudo apt-get install kmod libssl-dev checkinstall
git clone https://github.com/patjak/bcwc_pcie.git
cd bcwc_pcie
make clean
make
sudo make install
sudo depmod
sudo modprobe -r bdc_pci
sudo modprobe facetimehd
sudo nano /etc/modules
**add line "facetimehd", write out (ctl+o) & close**
