whenever i run rosdep install roboearth following error creeps in.

executing command [sudo apt-get install libcurl-ssl-dev]
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libcurl-ssl-dev is a virtual package provided by:
libcurl4-openssl-dev 7.22.0-3ubuntu4
libcurl4-nss-dev 7.22.0-3ubuntu4
libcurl4-gnutls-dev 7.22.0-3ubuntu4
You should explicitly select one to install.

E: Package 'libcurl-ssl-dev' has no installation candidate
ERROR: the following rosdeps failed to install
apt: command [sudo apt-get install libcurl-ssl-dev] failed

what should be the solution for this error then. this stack was compiling properly few days back.
Thanks :)

Which OS are you on ? and which version ?

maverick

I guess this method is only supposed to work with ubuntu 12.04 and rosdep 2. Because i didn't had any problem in ubuntu precise and rosdep.
Thanks for ur help i got it compiled on ubuntu 12.04

I forgot that apt-get install $virtual_package will fail if more than one package provides the specified virtual name. Depends: $virtual_package is, however, the correct way to depend on a virtual package when constructing a .deb package.

Since there's apparently no 'or' operator in rosdep, this script would work for non-.deb uses of "rosdep install":

curl_installed=0
for pkg in libcurl4-gnutls-dev libcurl4-openssl-dev libcurl4-nss-dev; do
  if dpkg -s $pkg >/dev/null 2>/dev/null
    then curl_installed=1; break
  fi
done
if [ $curl_installed = 0 ]; then
  sudo apt-get install -y libcurl4-gnutls-dev
fi

The .deb file, though, needs to have "libcurl4-openssl-dev | libcurl4-gnutls-dev | libcurl4-nss-dev" or "libcurl-ssl-dev".

thanks this will really help :)

The following debian packages are still depending on openssl-dev:
ros-groovy-simulator-gazebo
ros-groovy-robot-model
ros-groovy-resource-retriever
ros-groovy-object-recognition-core
Isn't that supposed to be fixed by now ?
