I want to install new KDE 4.10 on Ubuntu 12.04 (precise).
Can I install that from any repos (maybe not default repos) and without
kubuntu-desktop package? I want clean, fresh KDE without Kubuntu additions (and deletions).
Thanks in advance.
I came across this question from google asking how can I update KDE on (k)Ubuntu 12.04 without updating the server parts of the system.
So, I have Kubuntu 12.04.01 LTE, and there was KDE 4.8.5 installed (along Unity and a few others DMs)
.. and now I have same system with KDE 4.10 running on it without much problem so far.
Since the backports are from Kubuntu team, that does include kubuntu-desktop (in your situation it might be a better choice to first install kubuntu-desktop, then update from backports, and then remove extras you don't like too much).
Other option might be looking at http://techbase.kde.org/Getting_Started/Build
You can do this by doing the following:
Don't worry about the "kubuntu" in the ppa name. If you install the kde-standard package, it won't include kubuntu's customizations.
