    Hello everyone,

    I was about to recompile the kernel for Neo's board following the guide https://www.udoo.org/docs-neo/Advanced_Topics/Compile_Linux_Kernel.html and got stuck since the installation of the dependencies. I run Ubuntu desktop 18.04.5 and this is the error:

    $sudo apt-get install gawk wget git diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-dev xterm picocom ncurses-dev lzop gcc-arm-linux-gnueabihf
    ...
    The following packages have unmet dependencies:
    gcc-arm-linux-gnueabihf : Depends: gcc-7-arm-linux-gnueabihf (>= 7.4.0-1~)
    E: Unable to correct problems, you have held broken packages.


    if I continue anyway I get error while compiling:

    $ ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make zImage -j8
    CHK include/config/kernel.release
    CHK include/generated/uapi/linux/version.h

    I have just installed Ubuntu, so nothing else is in it.
    Can't go any further, I am a noob so any help will be really appreciated!
    Thank you
