Secure Boot in your BIOS should be disabled for this install to work since it is not signed. Go to the folder where you extracted the DroidCam and run sudo ./install Then you should be able to just type in droidcam from a terminal and run it normally.

Example:

terrance@terrance-ubuntu:~$ cd Downloads/droidcam/droidcam-64bit/
terrance@terrance-ubuntu:~/Downloads/droidcam/droidcam-64bit$ ls
droidcam  droidcam-cli  install  README  uninstall  v4l2loopback
terrance@terrance-ubuntu:~/Downloads/droidcam/droidcam-64bit$ sudo ./install

  • @mdrahman Try installing dkms sudo apt install dkms so the module can be inserted dynamically – Terrance Jan 07 '19 at 06:40
  • still Same. output is as before – Md Rahman Jan 07 '19 at 07:11
  • @MdRahman Ah, for the error see: https://askubuntu.com/a/762255/231142 Looks like you need to have Secure Boot disabled. – Terrance Jan 07 '19 at 14:32
