Leap 42.2 Beta 3 Network Installation:

Despite choosing "F2" installation language "Deutsch" at the first installation
screen (Network Installation ISO image on a CD-RW), the following installation
screens are all in English -- for example: "Language, Keyboard and License
Agreement".
 - At that screen the Language is "German - Deutsch" and the Keyboard Layout is
"German". The Keyboard Test functions correctly.
 - The License Agreement is in English with no possibility to view the German
translation.

At the following installation screens occasionally German language progress
strings appear.

At the "Suggested Partitioning" screen, the Partition information is in German.

At the "Clock and Time Zone" screen, the location is Europe/Germany.

At the "List of Online Repositories" screen the "Summary:" and "Description:"
text strings are in German. the following screen where the repositories are
added is also partially in German.

Once the (mostly English language) installation completes, a German language
system boots.
