[llvm-dev] arc install-certificate failure

[yao zhongxiao via llvm-dev]

When I add the "--trace" options, I got the following error message:
```
**yaozhongxiao at n13-022-168** : **~/workspace/compiler/llvm-project** $ arc

```
After checking the source code, it seems likes “conduit.ping” method failed,
but I can not get any other clues now.
```
50 public function run() { 51 $console = PhutilConsole::getConsole(); 52 53
$uri = $this->determineConduitURI(); 54 $this->setConduitURI($uri); 55
$configuration_manager = $this->getConfigurationManager(); 56 57 $config =
$configuration_manager->readUserConfigurationFile(); 58 59 $this->writeInfo(
60 pht('CONNECT'), 61 pht( 62 'Connecting to "%s"...', 63 $uri)); 64 65
$conduit = $this->establishConduit()->getConduit(); 66 try { 67 $conduit
->callMethodSynchronous('conduit.ping', array()); 68 } catch (Exception $ex)
{ 69 throw new ArcanistUsageException( 70 pht( 71 'Failed to connect to
server (%s): %s', 72 $uri, 73 $ex->getMessage())); 74 } 75
```
