Ubuntu – Ubuntu 17.10 Update: NVRM API Mismatch 384.11 kernel at 384.90

driverskernelnvidiaupdates

Today, I installed the software update from Ubuntu. Then on reboot, I never got to login screen. Something kept flashing on screen, but was too fast to see what it was saying.

Was able to ssh from another computer, dmesg says: "API mismatch: the client has the version 384.111, but this kernel module has the version 384.90. Please make sure that this kernel module and all NVIDIA driver components have the same version."

How could this mismatch happen, since my updates are via the software updater? Appears someone released a driver that the kernel wasn't expecting or some other error occurred.

How do I fix this?

Thanks.

I was able to fix this problem.

As it turns out, while I had been updating my system via the 'software updater', I was actually still running on the old beta 4.8 version of the kernel. uname -r showed me the version I was running. After installing newer kernel 4.13 and rebooting, it ignored the new version, continuing to boot under 4.8. Updated grub, then rebooted, and saw the 4.13 version on the grub menu, so I selected that. Then after it came up, I applied the NVIDIA security updates as before, and this time it worked.

Ubuntu – Nvidia API mismatch

Doing the following solved it for me on Ubuntu 12.04 64bit with 3.0.29 kernel. Hope it helps.

sudo apt-get purge nvidia-current
sudo apt-get install nvidia-current

Ubuntu – Nvidia driver updated – mixed versions of 304.88 and 319.32

Instead of installing the latest version, I recommend you to install Kernel which is meant for Ubuntu 12.04.3 LTS that is Linux Kernel 3.8.0.30. It is available in the repository so no need to go to some other place. Here is the steps to install Kernel 3.8.0.30 for Ubuntu 12.04.3 LTS.

Execute following commands in series(one by one, if you get any error in any command just comment for the command for which you got the error with the error message)
- Execute this to update repository:
```
sudo apt-get update
```
- Execute this to install Kernel 3.8.x(be careful, don't miss any character)
```
sudo apt-get install linux-generic-lts-raring linux-headers-3.8.0-30 linux-headers-3.8.0-30-generic linux-headers-generic-lts-raring linux-image-3.8.0-30-generic linux-image-generic-lts-raring
```
- Execute this to update grub:
```
sudo update-grub
```
- Execute this to re-configure all installed packages(It would take some time, so wait. If it fails, gives some error just proceed to next step)
```
sudo dpkg-reconfigure -a
```
- Execute this to restart your system:
```
sudo reboot
```
While restarting, you would see one more entry in Grub Entry for Linux Kernel 3.8.0.30 chose that.

Now Removing nvidia-304 and re-configuring nvidia-319

Follow these steps to do so.. I am assuming that nvidia-319 is currently installed in your system.

Open terminal and execute following commands to completely nvidia-304

sudo apt-get autoremove nvidia-304*
sudo apt-get --purge remove nvidia-304*
sudo apt-get autoremove
sudo apt-get autoclean

Then execute these commands to re-configure nvidia-319
```
sudo update-grub
sudo dpkg-reconfigure nvidia-319
```
if above command shows some error then try to replace nvidia-319 with nvidia-319*
```
sudo update-grub
sudo update-initramfs -u (it would take some time)
```
Then restart your system
```
sudo reboot
```
