Is there support for 16.04?

Hi there. Yesterday i upgraded my system to Ubuntu Gnome to 16.04 from Ubuntu Gnome 14.04. I' m also using some kde software, installed through "kde-full", like Dolphin.

The problem is that i don't have (after the upgradation) icons on Dolphin, except LibreOffice icons. I assume that the problem is that there is no support on this package (oxygen-gtk3) on this new Ubuntu version cause doing this on terminal:

sudo apt-get install kubuntu-default-settings && sudo apt-get install kde-config-gtk-style && sudo apt-get install gtk3-engines-oxygen

i received the following message(s):

Package gtk3-engines-oxygen is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'gtk3-engines-oxygen' has no installation candidate

I don't believe it 's a bug but, for a reason, this package can't be founded for this version of Ubuntu.
Do i have to wait to fix it or i must try an other way to install this package?
Thanks a lot,
Th
