Since updating ROS a few hours ago, ROS/catkin is broken

edit

Hi all,

A couple of hours ago, I updated my system (sudo apt-get update; sudo apt-get upgrade). Updates included a lot of Hydro updates as well. However since then, catkin_make always ends in an error. I tried:

• Reinstalling all ROS hydro packages
• Rebooting computer
• Create a new catkin ws and build the empty ws:
  • mkdir -p ~/catkin_ws/src
  • cd ~/catkin_ws/src
  • catkin_init_workspace
  • cd ~/catkin_ws/
  • catkin_make -> this gives an error again.
• Commenting out all my ROS related stuff in .bashrc and try again with the new catkin ws in a new terminal

The relevant lines of the error seem to be (find full output of cmake_ here: https://www.dropbox.com/s/sgw9whjn2cm... ):

CMake Error at /home/koenlek/catkin_ws/build/catkin_generated/order_packages.cmake:2 (message):

-- Configuring incomplete, errors occurred!

I checked the qt-ros and qt-create packages, it seems like nothing has changed in the last apt-get update (no changes on their github at least), so I think it is something else causing the issues.

Anybody has any ideas how to fix this? I need to perform some tests later today, so I badly need my system to get up and running again.

It seems that answers.ros.org is experiencing some spamming spree with loads of non-sense spambot messages coming in the latest hours. Is this some hacking/ddos attempt that has caused the servers to serve me some non-working updates?

I run Ubuntu 12.04 x64 with latest updates.
