plymouth-theme-ubuntu-text-dbgsym 0.8.8-0ubuntu17.2 (amd64 binary) in ubuntu trusty

 Plymouth is an application that runs very early in the boot process
 (even before the root filesystem is mounted!) that provides a graphical
 boot animation while the boot process happens in the background.
 .
 This package contains the default ubuntu-text text theme used when no
 support for a graphical theme is found on your system.
