Installing kernel module from AUR fails

General system Newbie
1

I have nct6687d-dkms-git installed, and I already used it. However since the latest update, it stopped working:

sudo modprobe nct6687
modprobe: FATAL: Module nct6687 not found in directory /lib/modules/5.16.9-zen1-1-zen

So I tried reinstalling it with paru -S nct6687d-dkms-git. However, I get the error:

==> dkms install --no-depmod nct6687d-dkms-git/r30.4f00ace -k 5.16.9-zen1-1-zen
Error!  Build of nct6687.ko failed for: 5.16.9-zen1-1-zen (x86_64)

Have you tried with the mainline kernel and/or LTS?

3

Yes, same problem with mainline.

4

Try clean building and reinstalling the package.

5

From what i understand, this would work with paru --rebuild nct6687d-dkms-git, right? Doing this leads to the exact same result.

What does the

say?

Did you try dkms autoinstall ?

9

There’s no error shown here.

Do you have any unmerged pacnew? Did you make any other changes to your system that you haven’t told us about?

10 
$ sudo dkms autoinstall
Error! Could not locate dkms.conf file.
File: /var/lib/dkms/nct6687d-dkms-git/r18.24f3a0f/source/dkms.conf does not exist.

source is a link to /usr/src/nct6687d-dkms-git-r18.24f3a0f, but that folder does not exist. What does exist, is /usr/src/nct6687d-dkms-git-r30.4f00ace

11

I just checked pacdiff, and there was nothing related.

I compiled and installed the tkg-kernel from git, but the problem also occurs when I don’t use it.

12

What does ls -l /var/lib/dkms/nct6687d-dkms-git/ return?

13 
ls -l /var/lib/dkms/nct6687d-dkms-git/
insgesamt 4
lrwxrwxrwx 1 root root 32 11. Sep 22:18 kernel-5.10.63-1-lts-x86_64 -> r18.24f3a0f/5.10.63-1-lts/x86_64

Also note my addition to the last post (I edited right at the moment when you answered)

Now that I see it, I remember, that I also removed the lts-kernel because I didn’t need it anymore. The fact that the link points to it is probably causing problems.

I’d remove the package, clean out any references to it that linger on disk, then rebuild and reinstall it.

15

Try this:
Delete the r18.24f3a0f folder, then dkms autoinstall

… and what @jonathon says :stuck_out_tongue:

I already tried removing it with paru -Rns, but that didn’t help.

The folder /var/lib/dkms/vhba-module/20210418/source is a dead link to /usr/src/vhba-module-20210418. That folder doesn’t exist, instead there is /usr/src/vhba-module-20211218 existing.

Looks like your DKMS setup got very broken at some point.

Remove as much DKMS stuff as you can, clean out /var/lib/dkms, and reinstall the various packages.

18

There is yet another module preventing dkms autoinstall from doing its job.

What’s the output of dkms status ?

19

Did you try to uninstall the package you try to make working?
Are you sure you know the state of your installation as of now?

I uninstalled all dkms modules, removed everything in /var/lib/dkms, and installed the modules again.

While installing, I got ==> ERROR: Missing 5.15.24-1-lts kernel modules tree for module errors.

So I installed LTS kernel again (why do I need to have it installed?!), and the installation worked without errors. The installation of nct6687d-dkms-git still failed, though.

$ dkms status

yes.

No, I’m very confused about what is going on.
