I'm trying to install composer in my Ubuntu 16.04 with PHP version 5.6.*.
I used:curl -sS https://getcomposer.org/installer | php. But it is giving me error as follows:
All settings correct for using Composer
Downloading...
The "https://getcomposer.org/versions" file could not be downloaded: failed to open stream: Connection refused

The "https://getcomposer.org/versions" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:

The download failed repeatedly, aborting.
I do not have composer installed previously.
