Boas I'm new in linux and i wan't knew how to find a package by a file that belong to it. i knew that is whith the apt-file, but when i do, apt-file search "file_name", i only see the message: Can't locate object method "host" via package "URI::_foreign" (perhaps you forgot to load "URI::_foreign"?) at /usr/bin/apt-file line 189. Could somebody say me what have i do? Amândio
