apt - How do I install a specific lower minor version of gcc using package manager?

I am running an Ubuntu 14.04-4 64bit. gcc --version returns

(Ubuntu 4.8.4-2ubuntu1~14.04.1) 4.8.4

Yet, I need version 4.8.2-10.
What I tried:

1. I found the specific gcc version in a debian snapshot repository.



2. I adapted my /etc/apt/sources.list to contain the following two lines only:

   
   

   deb http://snapshot.debian.org/archive/debian/20131213T160912Z unstable main
   deb-src http://snapshot.debian.org/archive/debian/20131213T160912Z unstable main
   




3. As suggested here I added the required key



4. I did sudo apt-get -o Acquire::Check-Valid-Until=false update


5. sudo apt-get remove gcc



6. sudo apt-get install gcc. This returned:

   
   

    ...
    Preparing to unpack .../gcc_4%3a4.8.2-1_amd64.deb ...
    Unpacking gcc (4:4.8.2-1) ...
    Processing triggers for man-db (2.6.7.1-1ubuntu1) ...
    Setting up gcc (4:4.8.2-1) ...
   

Unfortunately, gcc --version still returned
gcc (Ubuntu 4.8.4-2ubuntu1~14.04.1) 4.8.4

Removing and re-installing gcc-4.8 and gcc-4.8-base returned in an error (unmet dependencies) or a strange warning (uninstalling more than 700mb).

How can I install this specific gcc version?
