Removed dkms modules reappear in kernel upgrades [Solved]

My dkms status in linux-zen kernel version 6.7.9

hikmateustad@hikmateustad-dell ~ % sudo dkms status
acpi_call/1.2.2, 6.7.9-zen1-1-zen, x86_64: installed
nvidia/390.157, 6.7.9-zen1-1-zen, x86_64: installed
rtl88x2bu/5.13.1.r191.980d7cc, 6.7.9-zen1-1-zen, x86_64: installed
v4l2loopback/0.12.7, 6.7.9-zen1-1-zen, x86_64: installed

On upgrading to linux-zen 6.8.1 rtl88x2bu/5.13.1.r191.980d7cc and v4l2loopback/0.12.7, both error exited 10 while the other dkms modules passed.

rtl88x2bu/5.13.1.r191.980d7cc is the wireless modle for tp-link Archer T3UPlus AC 1300

Therefore I removed both the above errorenous modules from the dkms tree by issuing commands

hikmateustad@hikmateustad-dell ~ % sudo dkms remove v4l2loopback/0.12.7  
hikmateustad@hikmateustad-dell ~ % sudo dkms remove rtl88x2bu/5.13.1.r191.980d7cc

which gave feedback that those two modules were completely removed from the DKMS tree.

Mind you have not rebooted yet. Then I went to https://github.com/morrownr/88x2bu-20210702 and followed the instructions to install the wireless driver for tp-link Archer T3UPlus AC 1300 which went successfully. This adds the wireless driver rtl88x2bu back to the dkms tree

Next I 

sudo downgrade linux-zen linux-zen-headers

back to version 6.7.9. No reboot yet.

So now if I 

hikmateustad@hikmateustad-dell ~ % sudo dkms status
[sudo] password for hikmateustad: 
acpi_call/1.2.2, 6.7.9-zen1-1-zen, x86_64: installed
nvidia/390.157, 6.7.9-zen1-1-zen, x86_64: installed
rtl88x2bu/5.13.1, 6.7.9-zen1-1-zen, x86_64: installed

Going forward I proceed to install the latest arch linux kernel version 6.8.1 which installs correctly for dkms modules acpi_call, nvidia and rtl88x2bu but the removed rtl88x2bu/5.13.1.r191.980d7cc and v4l2loopback/0.12.7 reappear magically and fail again as you can see in the output.

Now I rebooted and fortunately my nvidia and wireless modules worked.

On the new kernel checking dkms status gave me 

hikmateustad@hikmateustad-dell ~ % sudo dkms status
[sudo] password for hikmateustad: 
acpi_call/1.2.2, 6.8.1-zen1-1-zen, x86_64: installed
nvidia/390.157, 6.8.1-zen1-1-zen, x86_64: installed
rtl88x2bu/5.13.1, 6.8.1-zen1-1-zen, x86_64: installed
v4l2loopback/0.12.7: added
rtl88x2bu/5.13.1.r191.980d7cc: added

So I removed the modules rtl88x2bu/5.13.1.r191.980d7cc and v4l2loopback/0.12.7 by issuing the sudo dkms remove command but

I would like to completely remove the rtl88x2bu/5.13.1.r191.980d7cc and v4l2loopback/0.12.7 modules from the dkms tree such that it does not reappear in the next kernel upgrade.

How do I achieve it?

Thank you in advance for your help.

Re: Removed dkms modules reappear in kernel upgrades [Solved]

Did you install the packages for those? What happens if you remove those?

As stated earlier, if I remove those manually using sudo dkms remove ... then those get removed from the dkms tree. This is confirmed by issuing the sudo dkms status command that those have been removed.

but

they reeappered during the 6.8.1 kernel upgrade as detailed in my post above. I do not want this.

So the question remains how can I delete those completely from the dkms tree so that they do not re-appear during a future kernel upgrade.

you must also remove the sources under /usr/src/

So should I just yank (delete) the rtl88x2bu-5.13.1.r191.980d7cc folder under sources? Waiting for confirmation .....

Suprisingly v4l2loopback does not show up?

Re: Removed dkms modules reappear in kernel upgrades [Solved]

dkms remove the modules first, then the package, then clear /usr/src from remnants.
Do you have th v4l2loopback sources in /usr/local/src? How did you install those?

Removing the local package deleted the rtl88x2bu directory in /usr/src.

There are no sources for v4l2loopback in /usr/local/src. v4l2loopback was installed with a fresh Arch install almost 3+ years earlier so I cannot remember how I installed it.

Regarding the v4l2loopback kernel error many cited installing v4l2loopback post installing the kernel. Unfortunately it did not work for me.
