in pop! OS

how do I Hey guys. How to update driver in to new kernel? Like I install Ubuntu pop os and install new kernel. But if I update driver using new kernel 6.8.12 it's get error say dkms not configure to this kernel.

### Assistant: Pop!OS + custom kernels + DKMS is one of those places where Linux stops being a pet and turns into a dragon.[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=3 "Edit section: Assistant: Pop!OS + custom kernels + DKMS is one of those places where Linux stops being a pet and turns into a dragon.") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=3 "Edit section's source code: Assistant: Pop!OS + custom kernels + DKMS is one of those places where Linux stops being a pet and turns into a dragon.")]

Pop!_OS + custom kernels + DKMS is one of those places where Linux stops being a pet and turns into a dragon. Let’s tame it methodically. 🐉

You’re seeing:

“dkms not configured for this kernel”after installing kernel 6.8.12 and then trying to rebuild a driver (usually NVIDIA, VirtualBox, ZFS, or some Wi-Fi module).
That error is not mystical. It means:

DKMS cannot find headers + build tools for that kernel, so it refuses to compile the module.
Let’s walk this as an engineer would: verify → fix prerequisites → rebuild → verify again.

I’ll assume Pop!_OS 22.04-based and kernel 6.8.12 is already installed.

#### 1️⃣ Pre-flight: verify the situation[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=4 "Edit section: 1️⃣ Pre-flight: verify the situation") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=4 "Edit section's source code: 1️⃣ Pre-flight: verify the situation")]

##### Check which kernel is actually running[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=5 "Edit section: Check which kernel is actually running") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=5 "Edit section's source code: Check which kernel is actually running")]

uname -r

You should see:

6.8.12-xxxx

##### Check which kernels are installed[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=6 "Edit section: Check which kernels are installed") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=6 "Edit section's source code: Check which kernels are installed")]

ls /lib/modules

Make sure 6.8.12-... exists here.

##### [[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=7 "Edit section: Check if headers exist") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=7 "Edit section's source code: Check if headers exist")]

ls /usr/src | grep 6.8.12

If nothing shows up, DKMS has nothing to compile against — that’s the core problem.

#### [[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=8 "Edit section: 2️⃣ Install the matching kernel headers") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=8 "Edit section's source code: 2️⃣ Install the matching kernel headers")]

Pop!_OS does not automatically install headers for custom kernels.

##### If your kernel came from Ubuntu mainline:[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=9 "Edit section: If your kernel came from Ubuntu mainline:") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=9 "Edit section's source code: If your kernel came from Ubuntu mainline:")]

sudo apt install linux-headers-6.8.12-*

If that fails:

sudo apt search linux-headers-6.8.12

Then install the exact package name it shows.

##### If you manually installed .deb files:[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=10 "Edit section: If you manually installed .deb files:") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=10 "Edit section's source code: If you manually installed .deb files:")]

You must also download & install the headers .deb from the same source.

Example:

linux-headers-6.8.12-060812-generic_*.deb

Then:

sudo dpkg -i linux-headers-6.8.12-*.deb

#### 3️⃣ Install build prerequisites (DKMS needs these)[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=11 "Edit section: 3️⃣ Install build prerequisites (DKMS needs these)") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=11 "Edit section's source code: 3️⃣ Install build prerequisites (DKMS needs these)")]

sudo apt install build-essential dkms linux-headers-$(uname -r)

Yes, even if you installed headers manually — this ensures toolchains are present.

#### 4️⃣ Reconfigure DKMS[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=12 "Edit section: 4️⃣ Reconfigure DKMS") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=12 "Edit section's source code: 4️⃣ Reconfigure DKMS")]

Now that headers exist, tell DKMS to rebuild.

##### See current DKMS state[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=13 "Edit section: See current DKMS state") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=13 "Edit section's source code: See current DKMS state")]

dkms status

You’ll probably see something like:

nvidia/550.67, 6.8.12-xxxx, x86_64: added (not built)

##### Force rebuild[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=14 "Edit section: Force rebuild") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=14 "Edit section's source code: Force rebuild")]

sudo dkms autoinstall -k $(uname -r)

or for a specific module:

sudo dkms install -m <module> -v <version> -k $(uname -r)

Example for NVIDIA:

sudo dkms install -m nvidia -v 550.67 -k $(uname -r)

#### 5️⃣ Rebuild initramfs (important)[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=15 "Edit section: 5️⃣ Rebuild initramfs (important)") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=15 "Edit section's source code: 5️⃣ Rebuild initramfs (important)")]

sudo update-initramfs -u -k $(uname -r)

This ensures the newly built modules are actually loaded at boot.

#### 6️⃣ Reboot[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=16 "Edit section: 6️⃣ Reboot") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=16 "Edit section's source code: 6️⃣ Reboot")]

sudo reboot

#### 7️⃣ Post-flight verification[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=17 "Edit section: 7️⃣ Post-flight verification") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=17 "Edit section's source code: 7️⃣ Post-flight verification")]

After reboot:

##### Check kernel[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=18 "Edit section: Check kernel") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=18 "Edit section's source code: Check kernel")]

uname -r

##### Check DKMS[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=19 "Edit section: Check DKMS") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=19 "Edit section's source code: Check DKMS")]

dkms status

Should now say:

installed

##### Check driver loaded (example: NVIDIA)[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=20 "Edit section: Check driver loaded (example: NVIDIA)") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=20 "Edit section's source code: Check driver loaded (example: NVIDIA)")]

nvidia-smi

or for any module:

lsmod | grep <module>

#### Why this happens (the physics under the hood)[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=21 "Edit section: Why this happens (the physics under the hood)") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=21 "Edit section's source code: Why this happens (the physics under the hood)")]

DKMS is basically a robot that:

1.   Finds /lib/modules/<kernel>/build
2.   Uses headers from /usr/src/linux-headers-<kernel>
3.   Compiles the module against that ABI

If step 2 is missing → DKMS refuses.

Pop!_OS normally ships kernels + headers together — but custom kernels break that assumption, so DKMS sulks.

#### TL;DR Fix[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=22 "Edit section: TL;DR Fix") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=22 "Edit section's source code: TL;DR Fix")]

sudo apt install linux-headers-6.8.12-* build-essential dkms
sudo dkms autoinstall -k $(uname -r)
sudo update-initramfs -u -k $(uname -r)
sudo reboot

##### A final philosophical note 😄[[edit](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&veaction=edit&section=23 "Edit section: A final philosophical note 😄") | [edit source](https://freemwiki.com/index.php?title=Openai/695cbbc2-66fc-800b-a35b-453e9bf11ccb&action=edit&section=23 "Edit section's source code: A final philosophical note 😄")]

The kernel is the skeleton of the OS. DKMS is the immune system. If you transplant a new skeleton but forget to update the immune system’s reference anatomy, it panics and refuses to attach the organs.

That’s all that’s happening here.

If you tell me which driver is failing (NVIDIA, VirtualBox, ZFS, Realtek Wi-Fi, etc.), I can tune the exact module commands so it compiles cleanly the first time instead of arguing with the dragon. 🐲
