How to Install KDE 4.5

KDE 4.5 is a milestone release that took several months to complete, fixing over 16,000 bugs. While it also added new features, the selling point of this release is the stability that typically comes with a x.5 version of KDE. The desktop, applications, and development platforms have matured, and many of the outstanding bugs have been resolved.

Not all Linux distributions will offer packages for KDE 4.5 upgrades, and none of them, at this time, are supporting them in their official repositories. This takes time, and most distros will include a version of KDE 4.5 with their next official releases. Therefore, keep in mind that the packages you are about to install may not be supported by your distribution. Some are included in their distribution’s “unstable” or “testing” repositories, while others are from third-party packagers.

I tried to include as many major Linux distributions as possible, but if I missed your favorite distro, feel free to add instructions for it in the comments section.

Kubuntu 10.04 packages are available in the backports repository, but they are not officially supported as part of the distribution. The development release (Maverick) 10.10 includes KDE 4.5 packages by default.

1. Add the following repository through KPackageKit or using apt-get in a terminal.

sudo add-apt-repository ppa:kubuntu-ppa/beta
Update: It should be the backport repository, not the beta.

2. Run a full upgrade using the graphical package manager or the following commands:

AlienBOB has published instructions on upgrading to KDE 4.5. Users should follow them to get the latest packages.


According to the Gentoo KDE guide, an official release of KDE 4.5 will not be made until KDE-PIM, which was delayed, is made available. This will probably be in KDE 4.5.1. There are also other bugs that Gentoo developers said KDE developers have not yet address. Users who still want KDE 4.5 can compile it themselves, as they normally would, and just use KDE-PIM 4.4.5. A full explanation is available at the KDE4 guide website.


At the time of this writing, PCLinuxOS developers were preparing KDE 4.5 packages, and they should be available soon. There was one bug in Konqueror that prevented YouTube from playing correctly, and they have already received help from KDE developers to fix it. You can receive updates by following them on Twitter.

Linux Mint

Linux Mint users can follow the Kubuntu instructions to upgrade to KDE 4.5. Simply add the Kubuntu backports ppa and run:

For other Linux distributions, FreeBSD, and other operating systems, you should check the official websites, wikis, announcement sections of forums, and mailing lists to see if KDE 4.5 will be included in their repositories and/or future releases.


  1. I like this but, I will say for Kubuntu 10.04, the repository to add is ppa:kubuntu-ppa/backports

    also, This worked fine on my Kubuntu home PC and Kubuntu laptop but, I get the “white screen of death” on a VM I am running at work.

  2. Debian? Debian has one of the best KDE desktops IMHO, because it is so default and malleable. The IRC channel says it will not be in Sid until Testing is released but that it would be in another repo at some point. I've read so many great things about KDE SC 4.5 that I am having a hard time waiting!

  3. Been testing KDE 4.5.1 on another distro, but am looking to give Kubuntu 10.10 beta a whirl. The new KDE feels more stable and a bit snappier, too.

  4. I’m don’t think your URL for opensuse is correct, at least it did not work for me. However this did work. Notice the extra stuff on the end of my URL

    zypper ar -f “”

    Adding repository ‘KDE 4.5.x Packages (openSUSE_11.3)’ [done]
    Repository ‘KDE 4.5.x Packages (openSUSE_11.3)’ successfully added
    Enabled: Yes
    Autorefresh: Yes

  5. And the correct command for the update is …
    zypper dup –from ‘KDE 4.5.x Packages (openSUSE_11.3)’

    and NOT zypper dup –from KDF

  6. Hi All,

    Can you please say the procedure of installing KDE 4.5 in CentOs 6?.
    I have already installed KDE 3.5.X  in CentOs 6…..
    Any idea?
