Why doesn't CURL want to load Composer?

Question

PHP

There was a problem installing composer-a, does not want to be installed. Installed all dependencies. I tried to put it globally in the project, but it turns out such a problem.

[email protected]:~$ curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
All settings correct for using Composer
[email protected]:~$ sudo curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
All settings correct for using Composer
[email protected]:~$

The download itself does not occur, but only All settings correct for using Composer and that's it. Doesn't give any errors.
Ubuntu 14.04
is on a virtual machine.
I increased the RAM a little, since before that there was an error "Segmentation error (memory dumped)"
Where to dig, who will tell you?
