    Muon Software Manager will not open.

    Hello,

    i got Kubuntu like a week ago and need some advice.

    Every time i klick on Moun Software Manager it crashes direcly after opening. Is this a common problem or just a setting missing?

    Thanks for reading

    Alex

    At here:

    Kubuntu 11.10, 32 bit.

    This is a clean new Kubuntu installation.
    Installed with the Alternate Kubuntu CD. Not Ubuntu CD and then installed the Kubuntu desktop.

    - installation KDE 4.7.1, 2011-10-14
    - upgrade KDE 4.7.2, 2011-10-26
    - upgrade KDE 4.7.3, 2011-11-19
    - upgrade KDE 4.7.4, 2011-12-28
    The KDE 4.7.4 is from the Kubuntu PPA: http://www.kubuntu.org/kde-sc-474
    The KDE 4.7.4 is moving/moved to the Oneiric proposed: http://kubuntuforums.net/forums/inde...opic=3119608.0

      Re: Muon Software Manager will not open.

      Hi,
      I also have an error when starting Muon:

      Executable: muon-installer PID: 1682 Signal: Segmentation fault (11)

      This started tohappen after an unsuccessful installation.
      Any ideas?

          Re: Muon Software Manager will not open.

          Is this a fresh install?

          My stable systems (Kubuntu installed a while ago) I'm having no problems with Muon.

          But I installed Kubuntu on my kids linux box Thursday, and after getting all the updates, I'm having the same behavior (Muon crashing).

            It would be helpful to add the Kubuntu/KDE/Muon versions

            Helpful to find a common cause why the muon is working/not working...

              If you mean an unsuccessful installation of Kubuntu, then start fresh and reinstall and ensure that it goes to completion "without error". You cannot expect anything to work properly if the operating system didn't get installed correctly.
              Windows no longer obstructs my view.

                Something to try

                The developer, Jonathan Thomas is blogging here: http://jontheechidna.wordpress.com/

                The experimental development packages (beta at the moment) are available: https://launchpad.net/~echidnaman/+a...t-experimental

                If the Oneiric release version Muon is crashing, you could try with the development version.


                Upgrade example

                1) adding the ppa, command line:
                Code:
                sudo add-apt-repository ppa:echidnaman/qapt-experimental
                Code:
                [sudo] password for oneline: 
You are about to add the following PPA to your system:
 QApt Experimental
 A place for packages for prerelease versions of QApt/Muon
 More info: [url]https://launchpad.net/~echidnaman/+archive/qapt-experimental[/url]
Press [ENTER] to continue or ctrl-c to cancel adding it

gpg: Total number processed: 1
gpg:        imported: 1 (RSA: 1)

                2) Updating the package database:
                Code:
                sudo apt-get update
                3) Checking the upgradeable packages:
                Code:
                /usr/lib/update-notifier/apt-check --human-readable
                Code:
                11 packages can be updated.
0 updates are security updates.
                4) Upgrading
                Code:
                sudo apt-get dist-upgrade
                Code:

The following packages will be upgraded:

 libqapt1 muon muon-installer muon-notifier muon-updater qapt-batch

11 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
                5) Testing



                Code:
                :~$ muon-installer -v
Qt: 4.7.4
KDE Development Platform: 4.7.4 (4.7.4)
Muon Software Center: 1.2.80 "Daring Dalek"
                Code:
                :~$ muon -v
Qt: 4.7.4
KDE Development Platform: 4.7.4 (4.7.4)
Muon Package Manager: 1.2.80 "Daring Dalek"
                Both Muons are working at here.


                Downgrade example

                The Muon upgrade is from a PPA, so there is a handy tool:

                Code:
                :~$ apt-cache show ppa-purge

Description: disables a PPA and reverts to official packages
 This program disables a PPA from your Software Sources and reverts your
 system back to the official Ubuntu packages. You can use this to return your
 system to normal after testing a new version from a PPA.
Homepage: [url]https://launchpad.net/ppa-purge[/url]
                It can be installed with the command:
                Code:
                sudo apt-get install ppa-purge
                Manual:
                Code:
                :~$ man ppa-purge
                Code:
                NAME

    -p PPA name
       Name of the PPA to be reset, the default value is ppa.

    -s PPA host
       Address of the repository server, the default value is ppa.launchpad.net.

                Downgrading the qapt-experimental packages.

                1) PPA purge command:
                Code:
                sudo ppa-purge ppa:echidnaman/qapt-experimental

                  OneLine, thanks for the clear examples. It worked for me.

                    Re: Muon Software Manager will not open.

                    HI
                    For possibly other situations.

                    Running the alpha of Precise Rekonq wanted to install the flash driver, but it couldn't.

                    When i tried to install something from Muon it said there was another instance of a package manager running. And that happened after restarts.

                    After a while I did dpkg-a in terminal, it showed the installer for flash trying to run, asked if I wanted to install flash, I said so and it installed and did a LOT of dpkging! and then Muon ran ok.

                    I might have looked in processes, but didn't think about it.

                    However, this is the beta of Precise so one expects stuff like this, but, it might be an idea for people that the above fix does not work for to check in processes and see what is going on.
