Is there a default Update Manager for Kubuntu? If there isn't can I install the Ubuntu Update Manager?

I know I can use

sudo apt-get update && sudo apt-get upgrade

but sometimes I get something like:

0 to install 0 to remove, 0 new, 0 upgraded and 3 not upgraded

Any way to fix this?

    There's nothing wrong with that.. what are the packages that are being put on hold?. – Uri Herrera Feb 10 '12 at 4:14
  • I'm not sure. It doesn't tell me. – Seth Feb 10 '12 at 4:22
  • @Seth to see on-hold packages the best and universal way is dpkg --get-selections | grep on-hold. – Braiam Aug 12 '13 at 22:00

Kubuntu & Muon

Kubuntu is an Ubuntu derivative. Information for Kubuntu can be found on the Kubuntu homepage. The Kubuntu 11.10 release notes says:

Muon Suite 1.2

The Kubuntu team is proud to present our new suite of tools for installing and managing software. Installing of .deb packages, updating, and software management is all part of this new, integrated suite, specifically designed to work with Debian style package management...

The kubuntu-desktop package is recommending (installing as default):

  • muon, package manager for KDE

  • muon-installer, utility for browsing, installing, and removing applications

  • muon-notifier, update notifier for KDE

The package muon is also recommending the muon-updater, an update manager for KDE.

The latest information of the Muon can be found from the developer's blog.

Apt - upgrade and dist-upgrade

The "not upgraded" packages could need to install some new packages. The "upgrade" action can't do this.

The apt manual page (man apt-get):

upgrade will

upgrade is used to install the newest versions of all packages currently installed...under no circumstances are currently installed packages removed, or packages not already installed retrieved and installed. New versions of currently installed packages that cannot be upgraded without changing the install status of another package will be left at their current version...

dist-upgrade will

dist-upgrade in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary.

So, the apt-get dist-upgrade command may remove some packages...


Update manager for Kubuntu is called muon-updater and I believe it's installed by default. Just press Alt-F2 and start typing 'muon-updater' there


Not always is install by default. I experienced that when you install a brand new (not upgrading from ubuntu) kubuntu the muon update manager is not install by default but only the muon discover. So I resolve this by going to the muon discover and in the search box type Muon you will see that the updater has to be install manually. Just press the install button for the muon software center. You will see the updater will get installed as well.

Furthermore if you want to get the latest update just go to left-lower corner (the k button) and click over there go to application-system-Sofware Updates and the updates will be prompted for you. Just follow the instructions.
