title: Apt-get can't install anything due to broken dependencies
body: <p>Whenever I run apt-get install for any package I get this error</p>
  
  <pre><code>➜  ~ sudo apt-get install clang-5.0
  
  Reading package lists... Done
  
  Building dependency tree       
  
  Reading state information... Done
  
  You might want to run 'apt --fix-broken install' to correct these.
  
  The following packages have unmet dependencies:
  
   gcc-7-multilib : Depends: libc6-dev-i386 (&gt;= 2.11) but it is not going to be installed
  
   libc6-dev-x32 : Depends: libc6-dev-i386 (= 2.25-2) but it is not going to be installed
  
  E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
  </code></pre>
  
  <p>And when I run sudo apt --fix-broken install I get this error</p>
