Summary

Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-4.15.0-1140-kvm 4.15.0-1140.145 linux-image-4.15.0-1156-aws 4.15.0-1156.169 linux-image-4.15.0-211-generic 4.15.0-211.222 linux-image-4.15.0-211-generic-lpae 4.15.0-211.222 linux-image-4.15.0-211-lowlatency 4.15.0-211.222 linux-image-aws-lts-18.04 4.15.0.1156.154 linux-image-generic 4.15.0.211.194 linux-image-generic-lpae 4.15.0.211.194 linux-image-kvm 4.15.0.1140.131 linux-image-lowlatency 4.15.0.211.194 linux-image-virtual 4.15.0.211.194 Ubuntu 16.04 ESM: linux-image-4.15.0-1156-aws 4.15.0-1156.169~16.04.1 linux-image-aws-hwe 4.15.0.1156.139 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.
