Droidcam/v4l2loopback device not found

Hello everybody, newbie to Linux, literally 3 days starting using it so maybe this problem is easy to solve but i don’t know how.

Well, my problem is that when I open Droidcam (which was installed from the Add/remove software from Manjaro) it gives me this error message:Screenshot_20210920_131813

I investigate a little and found out that I have to install the matching headers for the kernels, but I tried with the commands I found and it didn’t work. Here’s the one i used for example:

$ sudo pacman -Syu linux-latest-headers linux-lts-headers

And when i put this command in the terminal it gives me this error message:

warning: failed to retrieve some files
error: failed to commit transaction (failed to retrieve some files)
Errors occurred, no packages were upgraded.

By the way, the kernels i have installed is the version Linux 5.13.13 (linux513) and Linux 5.14.0 (linux514) which is the last version i have available.

Thanks for reading and hopefully responding, see ya!!

Please search before asking - the topic has been covered.

AUR PKGBUILDs are created for Arch - and some build scripts requires special attention and droidcam is one of them. Also the maintainer of the AUR script states that Manjaro is unsupported - my guess it is because of the headers dependency which packages has another naming schema on Manjaro than on Arch.

Closing this as a duplicate.
