The theme is missing cache files-I think through XFCE Startup or in the package's postinstall script you need to execute the command as said in the notification error triangle message thing:
"Warning: this icon theme has no cache file. You can create this by running gtk-update-icon-cache /usr/share/icons/elementary-xfce-darkest in a terminal emulator. TL;DR: add a postinst script to execute that command gtk-update-icon-cache /usr/share/icons/elementary-xfce-darkest ** Tags added: groovy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872313 Title: elementary xfce darkest icon theme missing cache file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/elementary-xfce/+bug/1872313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
