    Hash Sum Mismath while updating libcairo2 with Intel Graphics Update Tool on Yakkety

    Hello everyone,
    This afternoon I installed Intel Graphics Update Tool on my laptop running Ubuntu 16.10 Yakkety Yak. I also followed the guide at the bottom of the official page, because it gave me errors with the GPG keys.
    While upgrading, both through the tool and through the command
    Code:
    sudo apt full-upgrade
    , it gave me the following output:

    Code:
    Reading package lists...
    Building dependency tree...
    Reading state information...
    Calculating upgrade...
    The following packages will be upgraded:
      libcairo-gobject2 libcairo-script-interpreter2 libcairo2 libcairo2-dev
    4 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

    I tried with
    Code:
    sudo apt clean all
    ,
    Code:
    sudo apt clean
    ,
    Code:
    sudo apt autoclean
    . And I did
    Code:
    sudo apt update
    after that, of course.
    I also did
    Code:
    rm -rf /var/lib/apt/lists/*
    and updated, without success.
    Can someone help? Thanks.

    EDIT. It now works. They have fixed it, apparently.

    I was able to reproduce your problem following that link
    Try this as a temp workaround...this "should be fixed soon"
    for now you can go to Software & Updates, Click on "Other Software" tab and deselect or uncheck this update: "https://download.01.org/gfx/ubuntu/16.10/main/"
    Now try update/upgrade again.

    This solution works. Thank you! How long should I wait for?

    Your Welcome.
    You know this is just a guess here...but I would guess 2 to 4 days.
    If this has anything to do with Canonical (and I doubt it) be paitent, they have thier hands full ATM.
