Cannot install libclang-dev and build-essential

If i try to install libclang-dev and build-essential:

sudo apt install libclang-dev
sudo apt install build-essential

I get the following error (at bottom of page), but how can I install the correct libc6 I have already tried to swap to an older version, update & upgrade and

sudo dpkg --configure -a 
sudo apt-get -f install

None of it worked

Solution

  • That happens because there is no libclang-dev in the ubuntu apt package.

    you should look at this :

    enter image description here

    you should choose one of these:

    libclang-10-dev libclang-8-dev
    libclang-common-6.0-dev libclang-cpp10-dev libclang-cpp1-9 libclang-11-dev libclang-9-dev
    libclang-common-7-dev libclang-cpp11 libclang-cpp9 libclang-12-dev libclang-common-10-dev
    libclang-common-8-dev libclang-cpp11-dev libclang-dev libclang-6.0-dev libclang-common-11-dev
    libclang-common-9-dev libclang-cpp12 libclang-perl libclang-7-dev libclang-common-12-dev libclang-cpp10
    libclang-cpp12-dev

    you also can Search before installing something like :

    sudo apt-cache search libclang

    Please see How to use apt-cache search to find packages for more information.

    and be sure you should use sudo apt-get update before installing anything.

    For Unable to correct problems, you have held broken packages you should see this answer

    You can get a list of actual held packages with:

    dpkg --get-selections | grep hold If there are none, or none look related, then it's probably something else. Check carefully the output of the command you were trying when you got the error message, as there may be other clues in the full output from that command, aside from the error message.
