Hi hypper
We need more information.
I have no clue what you mean by "todays transition to plasma5"
What have you been using ? kde 4 ?, kde-next ?, xfce ?, etc
As far as I know, kde-plasma-desktop and plasma-widgets-addons are not on hold unless you put them on hold.
apt-mark showhold
will show you that.
Until we have more information, we can't help.
We need to see the output of
inxi -r
please
