can't insatll modules through dkms

when I run

sudo dkms install --no-depmod v4l2loopback/0.14.0 -k 6.13.8-arch1-1

I get only errors

Sign command: /usr/lib/modules/6.13.8-arch1-1/build/scripts/sign-file
Signing key: /var/lib/dkms/mok.key
Public certificate (MOK): /var/lib/dkms/mok.pub

dkms.conf: Warning! Zero modules specified.

Error! Bad conf file.
File: /usr/src/v4l2loopback-0.14.0/dkms.conf does not represent a valid dkms.conf file.

how can I fix this?

EDIT: also it threw some errors, when I installed linux-headers

Re: can't insatll modules through dkms

It specifically says that file is bad, what's in it?

That's obviously no good. Reinstall the package that includes that file.

it's v4l2loopback-dkms. And I can't delete it.

Error! The module/version combo: v4l2loopback/0.14.0 is not located in the DKMS tree.

there I tried to remove it with dkms remove

error: target not found: v4l2loopback-dkms

and there I tried removing through pacman

Re: can't insatll modules through dkms

And pacman.log shows v4l2loopback-dkms was installed? Between it not being in the database and that empty file, something went very wrong. You'll need to reinstall it, likely with https://wiki.archlinux.org/title/Pacman … )%22_error

Re: can't insatll modules through dkms

I never once said to remove it, why do you keep doing that? Just install/reinstall the package.
