title: When upgrading Angular 5 to 6, I get incompatible peer dependency (using ng update @angular/core)
body: <p>I am trying to update my Angular app from v5 to v6 following <a href="https://update.angular.io/" rel="noreferrer">this guide</a>.</p>
  
  <p>I have ran all these commands successfully:</p>
  
  <pre><code>npm install -g @angular/cli
  npm install @angular/cli
  ng update @angular/cli
  </code></pre>
  
  <p>The problem is that I get an error when running this command:</p>
  
  <pre><code>ng update @angular/core
                    Package "@angular/flex-layout" has an incompatible peer dependency to "rxjs" (requires "^5.5.0", would install "6.2.0").
                    Package "@angular/compiler-cli" has an incompatible peer dependency to "typescript" (requires "&gt;=2.7.2 &lt;2.8", would install "2.6.2")
  Incompatible peer dependencies found. See above.
  </code></pre>
  
  <p>I am not sure how to handle this &amp; I don't want to try things on my own to avoid breaking the app.</p>
  
  <p>Can someone please advise what to do?</p>
  
  <p>My current dependencies are as follows:</p>
