To update KDE on Kubuntu, first yous need to enable the "Kubuntu's backports repository"; every bit we have seen on the guide "How to manage additional repositories on Ubuntu", you can either either open the concluding and requite the following control:
sudo add-apt-repository ppa:kubuntu-ppa/backports
and then give the following control:
sudo apt-get update && sudo apt-become upgrade && sudo apt-get dist-upgrade
Or you lot tin open up Muon (K Menu->System->Muon), select "Source", "Configure Software Sources", "Other Software, and then "Add…"; finally insert this line:
deb https://ppa.launchpad.cyberspace/kubuntu-ppa/backports/ubuntu trusty chief
Of course if you are using a version of Kubuntu older than 14.04 Trusty Thar, you lot have to change the penultimate word of the in a higher place line with the corresponding showtime give-and-take of the nickname of the version of Kubuntu you are using (for example 'saucy' for Kubuntu 13.10 Saucy Salamander, 'raring' for Kubuntu 13.04 Raring Ringtail, and and then on).
In one case you added the "Kubuntu's backports repository", Muon will update its database and it volition propose the various updates for KDE; select them and click "Install".
Regardless if you chosen the command line or Muon, once the updated KDE has been installed on Kubuntu you have to reinitialize your current desktop session: if it has been just a modest KDE update, like from 4.13.1 to 4.13.2, a simple log off and log back in may exist enough, but if information technology has been a major KDE update like iv.12.ten to 4.xiii.10, information technology would be prophylactic to completely reboot your computer to exist certain that all KDE components are reloaded.
