16.04 - file -i test.xlsx returns application/octet-stream instead of real mime type - Ask Ubuntu 


$ file -i import_test.xlsx import_test.xlsx: application/octet-stream; charset=binary

the mime type should "application/zip" command returns "application/octet-stream". working in ubuntu 14.04. though, can't remember if have installed additional packages working.

is there packages need installed in order mime types recognized office files?

i have latest libfile-mimeinfo-perl.
