Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS (Available with Ubuntu Pro): linux-image-4.15.0-1175-azure 4.15.0-1175.190 linux-image-azure-lts-18.04 4.15.0.1175.143 Ubuntu 16.04 LTS (Available with Ubuntu Pro): linux-image-4.15.0-1129-oracle 4.15.0-1129.140~16.04.1 linux-image-4.15.0-1166-aws 4.15.0-1166.179~16.04.1 linux-image-4.15.0-1175-azure 4.15.0-1175.190~16.04.1 linux-image-aws-hwe 4.15.0.1166.149 linux-image-azure 4.15.0.1175.159 linux-image-oracle 4.15.0.1129.110 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.
