I would like to update my KDE Desktop. I am using Kubuntu 11.10 with KDE 4.7, but I would like to install KDE 4.8. I think that I have to add tne next PPA: kubuntu-ppa/backports, and then run sudo apt-get dist-upgrade.

Is the software in this PPA stable? If so, why is not a default repository?

Can I trust this PPA?

Thanks.

Software in PPAs is usually untested by anyone other then the PPA owner and users. ...and the PPA description tells you as much. –  mikewhatever Apr 12 '12 at 18:18
    
if it makes you feel better, I've been using that PPA for a couple of months now and the only issue I've had is with my KMix dying sometimes, a restart solves this –  Dirk Hartzer Waldeck Apr 13 '12 at 10:08

Ubuntu Stable Release Updates

https://wiki.ubuntu.com/StableReleaseUpdates

Stable release updates are automatically recommended to a very large number of users, and so it is critically important to treat them with great caution. Therefore, when updates are proposed, they must be accompanied by a strong rationale and present a low risk of regressions.

Kubuntu Backports

https://launchpad.net/~kubuntu-ppa/+archive/backports

PPA description

Backports of new versions of KDE and major KDE apps for Kubuntu which are either too large a change or not yet tested enough to go to Ubuntu Backports.

I think that the new version of the KDE is in the "too large category". The new backported KDE version is also build against the new version of the Qt.

Q&A

Can I trust this PPA?

The packages are backported by the same Kubuntu developers who are building the Kubuntu 12.04 packages.

But there is always the risk ( https://help.ubuntu.com/community/UbuntuBackports ):

When using Backports, it is important to understand that there is an inherent risk in backporting software. Although backported packages are tested by the community before they are included in the repository, there are very occasionally bad interactions with the older software on your system that are overlooked...
