Composer install failed

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
Retrying...
The "https://getcomposer.org/versions" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:
error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed
Failed to enable crypto
failed to open stream: operation failed
Retrying...

failed to open stream: operation failed
The download failed repeatedly, aborting.

I do not have composer installed previously.

Change the Export proxy from https to http

Open Terminal

    echo $https_proxy
// Change export proxy from 
    https_proxy=https://192.168.0.10:8080/
// to 
   https_proxy=http://192.168.0.10:8080/

cmd:: https_proxy=http://192.168.0.10:8080/

I experienced this problem while using Laravel Homestead after I’d accidentally emptied the contents of this file: /etc/ssl/certs/ca-certificates.crt

What fixed it for me was:

sudo apt-get purge ca-certificates 
sudo apt-get install ca-certificates

Open terminal and run php -r "var_dump(openssl_get_cert_locations());"

Note the location of default_cert_file. It might say \usr\local\ssl\cert.pem Verify that that file exists. If not, download the cacert.pem file from https://curl.haxx.se/ca/cacert.pem and place it in somewhere preferably in /usr/local/ssl

You now have a file is usr/local/ssl/cacert.pem

Open your php.ini and add the location of the file openssl.cafile=cacert.pem

Install composer

Run composer config --global cafile "/usr/local/ssl/cacert.pem"

I solved the issue by downloading https://curl.haxx.se/ca/cacert.pem and giving it's path in my etc/php/5.6/cli/php.ini and etc/php/5.6/apache2/php.ini.

Then after running sudo service apache2 restart && sudo apt install composer just worked fine.

It looks like a misconfiguration of PHP/openssl on your host.

My workstation is Ubuntu 16.04.3, php 7.0.22 and openssl-1.0.2g - the installer worked fine.

Try with TLS disabled: 

curl -sS https://getcomposer.org/installer | php -- --disable-tls
