Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 23.10 linux-image-6.5.0-1018-laptop 6.5.0-1018.21 linux-image-6.5.0-1019-raspi 6.5.0-1019.22 linux-image-6.5.0-1023-gcp 6.5.0-1023.25 linux-image-6.5.0-42-generic 6.5.0-42.42 linux-image-6.5.0-42-generic-64k 6.5.0-42.42 linux-image-gcp 6.5.0.1023.25 linux-image-generic 6.5.0.42.42 linux-image-generic-64k 6.5.0.42.42 linux-image-generic-lpae 6.5.0.42.42 linux-image-kvm 6.5.0.42.42 linux-image-laptop-23.10 6.5.0.1018.21 linux-image-raspi 6.5.0.1019.20 linux-image-raspi-nolpae 6.5.0.1019.20 linux-image-virtual 6.5.0.42.42 Ubuntu 22.04 LTS linux-image-6.5.0-1022-nvidia 6.5.0-1022.23 linux-image-6.5.0-1022-nvidia-64k 6.5.0-1022.23 linux-image-6.5.0-1023-gcp 6.5.0-1023.25~22.04.1 linux-image-gcp 6.5.0.1023.25~22.04.1 linux-image-nvidia-6.5 6.5.0.1022.30 linux-image-nvidia-64k-6.5 6.5.0.1022.30 linux-image-nvidia-64k-hwe-22.04 6.5.0.1022.30 linux-image-nvidia-hwe-22.04 6.5.0.1022.30 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
