Icon Themes no cache file

[Dave W]

I installed this elementary-xfce and one of the icon themes has

"Warning this icon theme has no cache file"

Than is suggests I can fix this by this command

gtk-update-icon-cache /user/share/icons/elementary-xfce-darkest 

I than type

sudo gtk-update-icon-cache /user/share/icons/elementary-xfce-darkest

I get this result

output gtk-update-icon-cache: No theme index file.  Its this a folder type or a config file?


Other icon themes have this issue on some if the icon themes. One is obsidian theme which I liked. I now have since removed. I can apply the same solution other icon themes.

Thanks
Dave
