Boot fails after: openSUSE-2018-788(1) Security update for glibc

About System: OpenSUSE Leap 15.0
KDE Plasma Version: 5.12.5
KDE Frameworks Version: 5.45.0
QT Version: 5.9.4
Kernel Version: 4.12.14-lp150.12.7-default
OS Type: 64-bit

I installed only openSUSE-2018-788 (1) Security update for glibc. Shutdown. Boot.

The last message I saw on the screen was “Starting Locale Service…”, after waiting approximately 60+ seconds, the boot appeared to move forward to a blank screen. I tried to open a Virtual Terminal to look at the log but none were available.

I restored the machine from a backup.

Since many thing may depend on glib it is best to get ALL the updates not just the glib
