    gfortran dependency hell

    I was trying to install an R package which said it couldn't find -lgortran. So I uninstalled gfortran. However, when I tried to install it again, I got the following error

    Code:
    gfortran : Depends: gfortran-4.7 (>= 4.7.2-1~) but it is not going to be installed
    When I tried installing gfortran-4.7

    Code:
    gfortran-4.7 : Depends: gcc-4.7-base (= 4.7.2-2ubuntu1) but 4.7.2-11precise2 is to be installed
    
                 Depends: gcc-4.7 (= 4.7.2-2ubuntu1) but 4.7.2-11precise2 is to be installed
    When I try installing gcc-4.7-base or gcc-4.7, it tells me they're already installed.

    What's happening here and how can I fix this?

    I'm running 12.10

    Thanks

    It could be happen if you try to instal a package from source. This hell of dependency always solved on my machine by installing from repo, with using Synaptic Package Manager.

    Re: gfortran dependency hell

    you might proceed as follows: open a Terminal window and type in sequence:
    Code:
    gpg --keyserver keyserver.ubuntu.com --recv-key E084DAB9
    gpg -a --export E084DAB9 | sudo apt-key add -
    gksudo gedit /etc/apt/sources.list

    then paste in the opened file the following line (or a similar one: see the link below):

    HTML Code:
    deb http://cran.mirror.garr.it/mirrors/CRAN/bin/linux/ubuntu precise/

    BTW:
    regarding to the R mirrors, you find their complete list here:
    http://cran.r-project.org/mirrors.html

    and finally type in a new Terminal window:
    Code:
    sudo  apt-get update -y && sudo apt-get upgrade -y && sudo  apt-get dist-upgrade -y && sudo apt-get dselect-upgrade -y
    sudo apt-get install -y r-base
