Updating curl manually on Ubuntu

I wanted to update curl, but the version available on 16.04 of Ubuntu was 7.47.0, (not the latest 7.57.0) so the nice apt-get method wasn’t an option.

Download the latest release from http://curl.haxx.se/download.html to your home directory:

wget http://curl.haxx.se/download/curl-7.57.0.tar.gz

Install the tools to compile this release:

apt-get install libtool
apt-get install make

Unpack the source code:

tar -xvf curl-7.57.0.tar.gz


cd curl-7.57.0 # enter the directory where curl was unpacked
./configure --with-ssl
make install

Update the system’s binaries:

mv /usr/bin/curl /usr/bin/curl.bak
cp /usr/local/bin/curl /usr/bin/curl

You are done :bowtie:! The following will display your version of curl.

curl -Vv

If you are using this in PHP, you should restart:

service apache2 restart # if using apache
service php7.1-fpm restart # depending on your version


I should add my initial run of this did not produce a curl that could handle https (!) or handle some common encodings. The first issue was solved with:

sudo apt install libssl-dev

and appending –with-ssl to the ./configure command used in compiling above.

./configure --with-ssl

The second through downloading zlib and compiling:

wget http://www.zlib.net/zlib-1.2.11.tar.gz
tar -xvf zlib-1.2.11.tar.gz
cd zlib-1.2.11/
make install

I then continued with the initial install from the compile section, using:

./configure --with-ssl --with-zlib

This time I could confirm they were both installed by having the https protocol present, and a zlib version displaying on the first line of:

curl -Vv
