I had the same problem myself. What i found is that there are 2 packages, a. python-rosdistro b. python-rosdistro-modules that were recently updated. These updates can only be installed with dpkg version 1.18 and above. This version is not supported by 14.04 and does not install. I have installed it in the snapdragon flight platform using the following steps

Change dpkg to 1.18.4

Since i am using the snapdragon flight platform i am downloading the armhf build. Download the correct version for your CPU arch

wget http://ports.ubuntu.com/ubuntu-ports/pool/main/d/dpkg/dpkg_1.18.4ubuntu1_armhf.deb wget http://ports.ubuntu.com/ubuntu-ports/pool/main/libs/libselinux/libselinux1_2.4-3build2_armhf.deb

Here we download dpkg1.18.4 and its dependancy and manually install them

sudo dpkg -i libselinux1_2.4-3build2_armhf.deb sudo dpkg --auto-deconfigure -i dpkg_1.18.4ubuntu1_armhf.deb sudo apt-get -y -f install

Then we install the necessary package sudo apt-get update sudo apt-get -y install python-rosdistro Installing python-rosdistro automatically installs python-rosdistro-modules package as well

Then we install apptitude to install ros sudo apt-get -y install aptitude

sudo aptitude install ros-indigo-ros-base While installing ROS apptitude will show there is system dependancy errors and give you options the order of commands are 1. No (n) 2. No (n) 3. Yes (Y) 4. Yes (Y)

If you follow this, then you will downgrade dpkg back to the old supported version and everything will go back to normal. I have only done this in a fresh install of ubuntu.
