Unable to upgrade Indigo because of ros-indigo-ipa-canopen
I was able to install ros-indigo-desktop-full
just fine following the install instructions for Ubuntu 14.04.
However, when I try and upgrade by running:
sudo apt-get update && sudo apt-get upgrade ros-indigo-* -y
I get the error:
The following packages have unmet dependencies:
ros-indigo-ipa-canopen : Depends: ros-indigo-ipa-canopen-core but it is not installable
Depends: ros-indigo-ipa-canopen-ros but it is not installable
E: Unable to correct problems, you have held broken packages.
I don't even have ros-indigo-ipa-canopen
installed. Why am I getting this error and how do I resolve it?
