peej Posted April 23, 2019 Share Posted April 23, 2019 I have read other thread regarding v4l2loopback kernel module installation. I got same problem like this message below ========================================= ------------------------------ Deleting module version: 0.10.0 completely from the DKMS tree. ------------------------------ Done. Unpacking v4l2loopback-dkms (0.10.0-1) over (0.10.0-1) ... Setting up v4l2loopback-dkms (0.10.0-1) ... Loading new v4l2loopback-0.10.0 DKMS files... dpkg: warning: version '3.4.113-sun8i 4.19.25' has bad syntax: invalid character in revision number Building for 4.19.20-sunxi64 Module build for kernel 4.19.20-sunxi64 was skipped since the kernel headers for this kernel does not seem to be installed. =================================== I am usng Nano PI neo2 with armbian 4.19.20. When I install the kernel-headers using armbian-config, the version of kernel-headers installed is 4.19.25. Either the kernel source I have installed using armbian-config is 4.19.25. I just guess the version mistach doesn't make me succeed build of v4l2loopback. But I can't figure out what to do with this error. Please give me some comment.
