The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1043-aws-fips 6.8.0-1043.45+fips1 Available with Ubuntu Pro linux-image-6.8.0-1044-gcp-fips 6.8.0-1044.47+fips1 Available with Ubuntu Pro linux-image-6.8.0-88-fips 6.8.0-88.89+fips1 Available with Ubuntu Pro linux-image-aws-fips 6.8.0-1043.45+fips1 Available with Ubuntu Pro linux-image-aws-fips-6.8 6.8.0-1043.45+fips1 Available with Ubuntu Pro linux-image-fips 6.8.0-88.89+fips1 Available with Ubuntu Pro linux-image-fips-6.8 6.8.0-88.89+fips1 Available with Ubuntu Pro linux-image-gcp-fips 6.8.0-1044.47+fips1 Available with Ubuntu Pro linux-image-gcp-fips-6.8 6.8.0-1044.47+fips1 Available with Ubuntu Pro 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.
