I am trying to install curl library. It is a dependency for the RCurl package in R. So I must install it for R to work properly. I tried:

$ sudo apt-get install libcurl4-opensll-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libcurl4-opensll-dev

I found a similar problem in the three links below. But they did not help solve my dilemma.

I need the following for Rcurl to work: sudo apt-get install libcurl4-opensll-dev.

    You have typo. It should "libcurl4-openssl-dev" instead of "libcurl4-opensll-dev"

For PHP:

install curl

sudo apt-get install php5-curl

restart apache

sudo apache2ctl restart

You can install Curl simply by :

sudo apt-get install curl libc6 libcurl3 zlib1g

Use following -

mkdir xxx
cd xxx

for 32 bit use-

wget http://packages.ubuntu.com/precise/i386/libcurl4-openssl-dev/download

For 64 bit use-

wget http://packages.ubuntu.com/precise/amd64/libcurl4-openssl-dev/download

For knowing the name of package_name.deb downloaded file use -


For Installation use -

sudo dpkg -i package_name.deb

Just write the name of the package instead of package_name.deb as you got it from previous command ls.

Hope it helped you.
