title: Updating SOCKS proxy via apt.conf doesn't update Network Manager>>Proxy section
body: <p><strong>Os:</strong> Ubuntu 16.10</p>
  
  <p><strong>What I'm trying to do:</strong> </p>
  
  <p>I've got external socks v5 server. I want to *send all local WEB traffic to socks server by doing this:</p>
  
  <ol>
  <li><p>ssh -D 1337 -f -C -q -N admin@socks_server_ip; #Connection no issues here</p></li>
  <li><p>ps aux | grep 1337 # I see PID related to this connection, no issues here as well</p></li>
  <li><p>Update /etc/apt/apt.conf as:</p></li>
  </ol>
  
  <p><strong>Acquire::socks::proxy "socks://user:pass@host:port/";</strong> #No issues in updating apt.conf as well</p>
  
  <p><strong>Problem:</strong></p>
  
  <p>When I'm done succesfully editing apt.conf file, I should be able to see changes in Network >> Proxy section listing socks proxy details something like this:
  <a href="https://i.stack.imgur.com/zrICl.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zrICl.png" alt="Network"></a></p>
  
  <p>BUT, even after updating apt.conf, I see this:
  <a href="https://i.stack.imgur.com/FeQNP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FeQNP.png" alt="enter image description here"></a></p>
  
  <p>And I can't access internet until or unless I <strong>manually</strong> set Network >> Proxy details. Anybody have any idea why this is happening?? Please suggest any solutions if possible. Thanks </p>
