Update curl on Ubuntu 14.04

update_curl.sh

#! /usr/bin/env bash

# Install any build dependencies needed for curl
sudo apt-get build-dep curl

# Get latest (as of Feb 25, 2016) libcurl
mkdir ~/curl
cd ~/curl
wget http://curl.haxx.se/download/curl-7.50.2.tar.bz2
tar -xvjf curl-7.50.2.tar.bz2
cd curl-7.50.2

# The usual steps for building an app from source
# ./configure
# ./make
# sudo make install
./configure
make
sudo make install

# Resolve any issues of C-level lib
# location caches ("shared library cache")
sudo ldconfig

EDITED: Great... Not working. Curl is giving no response.
Also PHP info is showing another version of curl: cURL Information | 7.47.0
I did sudo service apache2 restart

ubuntu@globerada:~$ curl -Vv

Thank you, it works. I have updated to latest (7.63.0 on 2019-01-09) because I had some problems with Curl 7.49 and Guzzle.

Steps for Ubuntu 16.04

touch update_curl.sh
chmod u+wx update_curl.sh
nano update_curl.sh

#! /usr/bin/env bash
sudo apt-get build-dep curl
mkdir ~/curl
cd ~/curl
wget http://curl.haxx.se/download/curl-7.63.0.tar.bz2
tar -xvjf curl-7.63.0.tar.bz2
cd curl-7.63.0
./configure --prefix=/usr
make
sudo make install
sudo ldconfig

./update_curl.sh

Thanks! It works! :)
Also I restarted my service in order to get visible the changes with the command:
systemctl restart apache2

@derylspielman thanks a bunch
