Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 25.04 linux-image-6.14.0-1017-gcp 6.14.0-1017.18 linux-image-6.14.0-1017-gcp-64k 6.14.0-1017.18 linux-image-gcp 6.14.0-1017.18 linux-image-gcp-6.14 6.14.0-1017.18 linux-image-gcp-64k 6.14.0-1017.18 linux-image-gcp-64k-6.14 6.14.0-1017.18 Ubuntu 24.04 LTS linux-image-6.14.0-1013-oem 6.14.0-1013.13 linux-image-6.14.0-1017-gcp 6.14.0-1017.18~24.04.1 linux-image-6.14.0-1017-gcp-64k 6.14.0-1017.18~24.04.1 linux-image-gcp 6.14.0-1017.18~24.04.1 linux-image-gcp-6.14 6.14.0-1017.18~24.04.1 linux-image-gcp-64k 6.14.0-1017.18~24.04.1 linux-image-gcp-64k-6.14 6.14.0-1017.18~24.04.1 linux-image-oem-24.04 6.14.0-1013.13 linux-image-oem-24.04a 6.14.0-1013.13 linux-image-oem-24.04b 6.14.0-1013.13 linux-image-oem-24.04c 6.14.0-1013.13 linux-image-oem-6.14 6.14.0-1013.13 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.
