    Skype stopped working on Ubuntu 10.10

    Hello,

    I am running ubuntu 10.10. I observed that skype has suddenly stopped working. I am unable to figure out what update has caused it.

    When I run:
    $ /usr/bin/skype
    /usr/bin/skype: symbol lookup error: /usr/lib/libQtNetwork.so.4: undefined symbol: _ZN16QIODevicePrivate4peekEPcx

    I found this error on ubuntu skype documentation: https://help.ubuntu.com/community/SkypeTroubleshooting. But the comments there do not help me.

    On searching on the net, I found the following interesting command:

    sudo ldconfig
    sudo apt-get install libqtgui4

    I tried it. But it did not help me ! Any suggestions to get this work? Your help is really appreciated. Thanks!

    Re: Skype stopped working on Ubuntu 10.10

    I've had this happen.

    Uinstall skype. Use synaptic package manager.

    sudo apt-get install synaptic
    gksu synaptic

    Then search for skype, right click on it and select "mark for complete removal".

    Clean the skype configuration files with Ubuntu Tweak package/config cleaner.. Then use bleachbit to clean your OS.

    sudo apt-get install bleachbit

    And then use that to really give your system a good cleaning, make sure not not accidentally delete your passwords with it...

    Then reinstall skype.

    sudo apt-get install skype

    For more information on cleaning your system:

    https://debianhelp.wordpress.com/201...nce-in-ubuntu/

    Most users don't know that it is a good idea from time to time either.

    skype has stopped working on ubuntu 10.10

    Hello All,

    Suddenly skype has stopped working on ubuntu 10.10. (Actually, earlier I posted this thread on main ubuntu general forum as well. But I think it was removed from there).

    When I run the command:
    $ /usr/bin/skype
    /usr/bin/skype: symbol lookup error: /usr/lib/libQtNetwork.so.4: undefined symbol: _ZN16QIODevicePrivate4peekEPcx

    So any suggestion as to how to get rid of this error? Thanks!

    Re: Skype stopped working on Ubuntu 10.10

    Dear Oldtimer,

    Thanks for the reply. I tried running bleachit. It executed partially. Then it got hung in between. I closed it manually.

    When I installed skype again and tried launching it was giving the same error. So I don't know what to do. Any other suggestions?

    Thanks

    Re: skype has stopped working on ubuntu 10.10

    Skype quite often gets out of sync with the library versions installed on Ubuntu. The best solution is to download the static version from the Skype website - this is completely self-contained and comes with all the libraries it needs for itself, so it should work on any system.

    http://www.skype.com/intl/en-gb/get-...omputer/linux/

    The Static version is the last entry in the list when you hover over the Download Now button.

    Steve.
