+Hey, 

+Ich bin's,  $sitename.   

+Die Friendica-Entwickler haben gerade Update $update freigegeben, 

+aber als ich es installieren wollte, ist irgendetwas schief gegangen.  

+Das sollte schnell repariert werden und alleine schaffe ich es nicht. 

+Wende dich bitte an einen Friendica-Entwickler, wenn du mir nicht selbst helfen kannst. 

+Meine Datenbank könnte ziemlich durcheinander sein. 

+

+Die Fehlermeldung ist '$error'.   

+

+Tut mir leid,

+but when I tried to install it, something went terribly wrong.  

+This needs to be fixed soon and I can't do it alone. Please contact a 

+friendica developer if you can not help me on your own. My database might be invalid.
