    At the same time cannot import or export

    I get this error:
    This webpage is not available

    The webpage at chrome-extension://invalid/ might be temporarily down or it may have moved permanently to a new web address.

    Error 2 (net::ERR_FAILED): Unknown error.

    … while in Google Chrome all works fine.

    I am referring to all in latest versions

    Tested also the 3 beta version to no avail.

    Any idea?



    Which version of Chromium do you use?


    Cprq Ceperche

    Version 20.0.1132.47 Ubuntu 12.04 (144678)


    that is now the latest in Ubuntu/Lubuntu



    Please install 21.x or later.

    thank you, but that is the latest in Ubuntu sources. otherwise i might just use google chrome. i will try to get a new version of chromium for linux although i do not know how exactly. could I not install instead  an older version of x notifier ?


    is that possible and if yes, what would that be?

    thnx for your quick reaction




    If you Google, there are ways to add a 3rd party source… for later Google Chromium versions.
    (Such as from Alex Shkop… a python developer.)

    I got a mail answer from RpD that I cannot see here regarding a link for beta and dev versions of Chromium
    The link is this

    Also, in order to add PPA for dev versions, here.





    I edited my post… as the link I had was to the same Chromium page… which is only version 18.

    The PPA link is a 3rd party developer… and here’s his page (he has links for both ‘stable’ and ‘dev’ releases:

    Thank you all.

    There is in fact an unofficial stable release that is newer than the one in the Ubuntu official sources and up-to-date with X-notifier and Google Chrome versions.

    To install, the Terminal commands are:


    sudo add-apt-repository ppa:a-v-shkop/chromium

    sudo apt-get update

    sudo apt-get install chromium-browser

    This solves the problem.



    Solution did not work for me:


    jb@Compaq-PC:~$ sudo add-apt-repository ppa:a-v-shkop/chromium

    [sudo] password for jb:

    You are about to add the following PPA to your system:

    While Chromium Team won’t release new versions of Chromium browser I will try to maintain more-or-less fresh releases of Chromium
