Hallo,

EIS Vers.: 	2.8.15

Diese Nachricht bekomme ich per Email

/usr/bin/in.wget: error while loading shared libraries: libidn2.so.4:

/usr/bin/in.grep: /tmp/index.txt: No such file or directory

Bei Update local database kommt diese Meldung

/usr/bin/in.grep: /tmp/index.txt: No such file or directory
