i think thats because wily isnt officially released
now im thinking to return back to 15.4 but with plasma 5.4 ... how ??

The errors are because you have added ppa's that do not provide packages for 15.10. As a new user, I would suggest not adding ppa's right off the bat, especially when using a pre-release version.

If you really really want plasma 5.4 in Kubuntu 15.04, you would have to wait for it to be in 15.10 first, then it may be backported to 15.04.

You have atm plasma 5.4 beta in wily. 5.4 final will be uploaded to wily soon, you don't need backports ppa (which is not yet available for wily).

For other Kubuntu specific questions, go to https://www.kubuntuforums.net/forum.php and register there. We are very friendly community

thanks guys
i think i will use this version until final release in October
what about plasma addons ??

By 'plasma addons' what are you specifically trying to install? There is no package by that name.
there are some like:
plasma-widgets-addons
plasma-dataengines-addons
plasma-wallpapers-addons
kdeplasma-addons-data

All these are built from the main source called kdeplasma-addons, and iirc most if not all theses are installed by default.

i was talking about dashboard introduced in latest 5.4 plasma release
you can ignore it right now because i installed ubuntu 15.4 (again) and started installing plasma by typing this in my terminal
sudo apt-get kubuntu-desktop
then
sudo apt-get update
and
sudo apt-get upgrade
then rebooted and now im facing black screen with cursor
i just rebooted again and went to advanced ubuntu and typed something like Linux generic upstars
well its working but after a reboot i face again a black screen
what i have to do now??

No idea on what to do, but when updating in the terminal, you should use sudo apt-get dist-upgrade (or sudo apt full-upgrade) else you will not get all the updates

Thank you , I managed to solve it by removing plasma and install it again
The problem here is that its not easy to uninstall a program like in windows
I remember its the 5th time I have to install ubuntu again since one week !
