Looks like the error was due to linux-headers-6.14.0-27-generic not being installed at the time of trying to upgrade your NVIDIA driver’s kernel modules packages. But this package did get installed in a follow-up software update. If it were my system I’d probably next try

sudo dpkg --configure -a

… and if that exits without error and doesn’t help, check if the selection in Software & Updates > Additional Drivers for your NVIDIA driver is still the same selection you made when you first installed the NVIDIA driver?

Thanks, the command exited without any error. But it didn’t fix the issue.

I went to Additional Drivers and installed the top most driver, which said proprietary, tested. It works

Had the same problem after an update (today, July 31). No network anymore, no connection with second screen…
Looking in Synaptic, I noticed that indeed the package
linux-modules-extra-6.14.0-27-generic
was not installed. I marked it for installation. I did a “Mark all upgrades” too, which added a few packages of the 6.14.0-27 family, did the update, and it fixed my problems.
Thanks!!!

Hi alain,

I was wondering what the exact commands you used for this were as I am currently struggling with the same issue here.

Tried this? @marvas1l

I used synaptic and checked the package: linux-tools-6.14.0-27-generic (6.14.0-27.27)
I also hit the “Mark all upgrades” button, which checked a few other packages.

Here is the log:
