Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS linux-image-5.4.0-1119-fips 5.4.0-1119.129 Available with Ubuntu Pro linux-image-5.4.0-1145-aws-fips 5.4.0-1145.156+fips1 Available with Ubuntu Pro linux-image-5.4.0-1148-gcp-fips 5.4.0-1148.157+fips1 Available with Ubuntu Pro linux-image-aws-fips 5.4.0.1145.92 Available with Ubuntu Pro linux-image-fips 5.4.0.1119.116 Available with Ubuntu Pro linux-image-gcp-fips 5.4.0.1148.90 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.
