Update instructions
The problem can be corrected by updating your system to the following package
versions:
Ubuntu 19.04
linux-image-5.0.0-1014-aws - 5.0.0-1014.16
linux-image-aws - 5.0.0.1014.15
To update your system, please follow these instructions: https://
wiki.ubuntu.com/Security/Upgrades .
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.
