    Hi Aniket,

    Are you asking about upgrade process from 13.10 to 14.04 or about the fresh installation?

    For Upgrade, it all depends on your internet speed :). If you have high speed internet, then it will take minimum 30 min or more than that. For fresh installation, all will take around 30 min.

    I did the update from 13.10 to 14.04 yesterday on my moms computer…however I did it all through terminal, none of it went through a pop up screen. The download displayed everything as if everything was running smooth through the terminal window. Then it asked me to reboot (yn) to which I hit y then enter. NOW… it boots to the login screen, sits for about 5 to 7 seconds, then the screen scrambles rendering the machine useless. Is there anyway to revert to the previous version of Ubuntu at all or do I have to reimage the machine again?

    Hi Kuldeep,
    thanks for the help, but unfortunately it didn’t work.


  5. Kuldeep says:

    I think there may be some issue with your source.list file or with the server from which it is fetching updates.

    Let us try once more :).
    Please take backup of your source.list and generate new one from http://repogen.simplylinux.ch/index.php.

    Hope this may help :).

    Hi Kuldeep,
    thanks for your help,
    I get this error after I ran apt-get update

    W: Failed to fetch bzip2:/var/lib/apt/lists/partial/it.archive.ubuntu.com_ubuntu_dists_saucy-updates_main_binary-amd64_Packages Hash Sum mismatch

    W: Failed to fetch bzip2:/var/lib/apt/lists/partial/it.archive.ubuntu.com_ubuntu_dists_saucy-updates_universe_binary-amd64_Packages Hash Sum mismatch

    E: Some index files failed to download. They have been ignored, or old ones used instead.

  7. Kuldeep says:

    Try below steps and check if it help..

    cd /var/lib/apt
    sudo mv lists lists.old
    sudo mkdir -p lists/partial
    sudo apt-get update

    This will rebuild the cache.

    Hi Kuldeep,
    it was clear since the beginning that there was a library conflict, but it is pretty tough to fix it.
    I am wondering why it is so complicate and contorted to update Ubuntu…


  10. Giuseppe says:

    Well, when I run update-manager -d I get this error:

    /usr/bin/python3: symbol lookup error: /usr/bin/python3: undefined symbol: XML_SetHashSalt
