I tested on three variants: CentOS 7, Source Mage, Ubuntu 20.

What does your `file -i` say about that file? I get 'XZ compressed
data' just fine with any instance of 'file', but the MIME type matching
doesn't seem to work for XZ (works for others!) with it being installed
from pkgsrc.

Specifically, on Source Mage, where I got file 5.40 from both sources,
I get this (the 'file' tool is from pkgsrc here):

$ file -m /usr/share/misc/misc/magic  -i adwaita-icon-theme-42.0.tar.xz 
adwaita-icon-theme-42.0.tar.xz: application/x-xz; charset=binary
$ file -m /stuff/pkg/share/misc/magic -i adwaita-icon-theme-42.0.tar.xz 
adwaita-icon-theme-42.0.tar.xz: application/octet-stream; charset=binary

The magic database makes a difference. It seems slightly less useful
when installed with pkgsrc.


Alrighty then,

Thomas
