Hi all I installed Koha 3.8.1. I got the following error while installing the german translation: koha@...:/usr/share/koha/misc/translator$ perl translate install de-DE Use of uninitialized value $key in hash element at /usr/share/perl5/Locale/PO.pm line 466, <IN> line 97052.

There is a similar error with it-IT: koha@...:/usr/share/koha/misc/translator$ perl translate install it-IT Use of uninitialized value $key in hash element at /usr/share/perl5/Locale/PO.pm line 466, <IN> line 17234.
