I'm trying to install build-essential using sudo apt-get install build-essential like I'm supposed to. It returns with the error

    The following packages have unmet dependencies:

     build essential : Depends: g++ (>= 4:4.4.3) but it is not going to be installed

    E: Unable to correct problems, you have held broken packages.

I have tried to use a few different fixes, like sudo apt-get install -f and sudo apt-get update as well as sudo apt-get upgrade but none have fixed the packages. When using sudo apt-get install -f this is what terminal tells me.

    The following packages were automatically installed and are no longer required:

      linux-image-3.19.0-25-generic linux-image-extra-3.19.0-25-generic

    Use 'apt-get autoremove' to remove them.

Other options return nothing.
I looked up a few other guides and questions, but none worked. I tried dpkg -i to try and let it install the dependencies for me, I tried following the labrynth myself and installing the dependencies by hand, but I just got more and more dependencies until I couldn't find the light at the end of the cold tunnel of dependencies. Is there an easy way to install build-essential through terminal that I'm not using, or is there a command that can install this long list of dependencies for me? I think I've included all the information that you'll need. This is a link to the dpkg -i guide that I tried-- How to let `dpkg -i` install dependencies for me? If there is additional information needed I can get it to you!

EDIT:

Here is the output of apt-cache policy build-essential g++.

    build-essential:

I also ran someone else's solution and it didn't work, but I noticed something interesting in the code so I ran sudo apt-get dist-upgrade a second time to get the information on its own. Here's what I got. I'm not sure what it means or how to fix it. If anyone can answer any of the multiple questions here that'd be very helpful! Thank you!

I tried to run sudo apt-get updates and sudo apt-get install -f after I saw this, but I just got the same output as before.
