I have installed Unity 3d Linux version, but the icon associated with the .unitypackage is not showing correctly. It always shows the wine icon. I have totally removed Wine, but the icon is still showing. I really appreciate any help.

  • Can you paste the output of file -b --mime-type FILENAME? – Bilal Elmoussaoui Mar 2 '16 at 14:42
  • application/gzip – Praveen Mar 9 '16 at 16:49
  • How did you installed Unity 3D ? the mimetype is not correct; try asking in Unity3D forum – Bilal Elmoussaoui Mar 9 '16 at 21:54
  • downloaded from forum.unity3d.com/threads/… – Praveen Mar 19 '16 at 5:10
  • Oh sorry, Mime type is : application/x-wine-extension-unitypackage – Praveen Mar 23 '16 at 13:11

To get the file extension you can use:

file -b --mime-type FILENAME

in this case : application/x-wine-extension-unitypackage

After that, copy the icon you need to use to /usr/share/icons/ICONTHEME in the mimetypes folder with this file name application-x-wine-extension-unitypackage

Rebuild the icon cache using sudo gtk-update-icon-cache -f /usr/share/icons/ICONTHEME and the new icon will be used.

  • Thank you very much, successfully changed the icon. anyway still need to fix the mime type, up-voted :) – Praveen Mar 23 '16 at 16:31
  • The mime type is related to the application you're using; Pantheon files (File manager) just shows the icon associated to the mimetype, maybe Unty 3D is not saving the files correctly. Trying reporthing that upstream. – Bilal Elmoussaoui Mar 23 '16 at 16:51
