  1. Tnx for this nice tutorial.
    I can’t suspend my laptop after upgrading to Ubuntu 14.04.2.
    How can I fix it?
    (I have a Lenovo z510)

  2. Hi, could you help me, my pc says I am running 14.04.2 but I have Kernel 3.13. I tried to add the packages using the command above but I keep getting this error:

    Some packages could not be installed. This may mean that you have
    requested an impossible situation or if you are using the unstable
    distribution that some required packages have not yet been created
    or been moved out of Incoming.

    • @REW, open Software & Updates utility from the Dash or App Menu, then navigate to Updates tab. There are 4 check-boxes under “install updates from”, make sure the first two “trusty-security” and “trusty-updates” are enabled.

      To avoid umet dependencies, you may disable all third-party PPA repositories under Other Software tab.

      Finally update system cache before installing new kernel and X stack:

      sudo apt-get update

    Thank you so much Ji m for the huge help. Now I have Ubuntu v14.04.2 LTS and with the new kernel v3.16.0-30 generic.

    It’s so easy to do all the steps.

  4. Be careful before installing it, it breaks the wifi of computers with Qualcomm network. I fixed it by following this answer on askubuntu

    • You may have installed opera and added its repository in your system. Run below command to get the keyring:

      wget -O - http://deb.opera.com/archive.key | sudo apt-key add -
