    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.04 LTS:
      linux-image-4.15.0-1047-aws     4.15.0-1047.49
      linux-image-aws                 4.15.0.1047.46
    
    Ubuntu 16.04 LTS:
      linux-image-4.15.0-1047-aws     4.15.0-1047.49~16.04.1
      linux-image-aws-hwe             4.15.0.1047.47
    
    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.
