Arch Linux User Repository

Same problem with @ManjaroUsar. Using 5.6.8-arch1-1.

It gives me a ==> ERROR: One or more files did not pass the validity check! when I install it (I tried with yay and the pamac gui). I use manjaro on Linux 56 kernel, and I had the headers installed. The download snapshot method gave the same error.

I'll do some extra testing on Arch and if it works I'l add the patch. (As soon as I am behind my terminal).

montefuscolo's fix worked for me. Thanks. 5.4.35-1-Manjaro.

I did this changes on Manjaro

It shows /lib/modules/5.6.7-1-MANJARO/extramodules/v4l2loopback_dc.ko.gz: Unknown symbol in module, but it works.

sudo modprobe v4l2loopback_dc

Fixed the Unknown symbol in module error for me after install. And it works after that.

I agree with @Scindix

I'm on arch, vanialla kernel and have the same error.

Also while removing the package:

The v4l2loopback_dc doesn't get updated with the kernel properly. You have to reinstall droidcam everytime you kernel updates... Would be nice, if dkms would be implemented
