Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1010-gkeop 6.8.0-1010.12 linux-image-6.8.0-1023-gke 6.8.0-1023.27 linux-image-6.8.0-1028-gcp 6.8.0-1028.30 linux-image-6.8.0-1028-gcp-64k 6.8.0-1028.30 linux-image-gcp-64k-lts-24.04 6.8.0-1028.30 linux-image-gcp-lts-24.04 6.8.0-1028.30 linux-image-gke 6.8.0-1023.27 linux-image-gkeop 6.8.0-1010.12 linux-image-gkeop-6.8 6.8.0-1010.12 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.
