Answer 1

You have to compile curl with sftp support first.

Download and unpack the curl source. After that:

sudo apt-get install build-essential debhelper libssh2-1-dev
sudo apt-get source libcurl3
sudo apt-get build-dep libcurl3

cd curl-x.xx.x/debian

nano rules

find and replace "--without-libssh2" with "--with-libssh2"

cd ..

sudo dpkg-buildpackage

cd ..

sudo dpkg -i curl_xxxxx.deb
sudo dpkg -i libcurl3_xxxx.deb
sudo dpkg -i libcurl3-gnutls_xxxx.deb

Update the commands with the adequate versions, ofcourse. More info here.
