ubuntu nvidia update issues

I had an issue where Ubuntu only detected 1 of my 3 screens, so I decided to do an update:

sudo ubuntu-drivers autoinstall
sudo reboot

This fixed it, but afterwards I didn’t have wifi / ethernet anymore. The settings to even find wifi was completely gone.

Then I found this thread after googling sudo ubuntu-drivers autoinstall wifi gone where someone had said the following:

You need to install linux-modules-extra-5.4.0-52 by running sudo apt install linux-modules-extra-5.4.0-52-generic It is weird that it didn’t install automatically on a kernel upgrade. Probably you’ve interrupted an upgrade.

Now this sounds like a quick fix until you realize, that I can’t do that without wifi.

So I booted into a previous kernel version to try and fix this.

And I fixed it by running the following in the previous kernel version:

sudo apt install linux-modules-extra-6.14.0-35-generic

But this won’t work for everyone. You need to check your kernel version first:

ls /boot | grep vmlinuz

And I got this output:

vmlinuz
vmlinuz-6.14.0-33-generic
vmlinuz-6.14.0-34-generic
vmlinuz-6.14.0-35-generic
vmlinuz.old

So that is why my command is sudo apt install linux-modules-extra-6.14.0-35-generic instead of sudo apt install linux-modules-extra-5.4.0-52-generic.

(pick the one that you are trying to update to, not the one you are currently using on the previous kernel version)
