2011-10-11 04:59:41 -0500	marked best answer	Ubuntu Lucid, cannot install ROS electric Your configuration looks valid to me. Sometimes the ROS Ubuntu package repository gets into an invalid state while being updated. If so, it should work again fairly soon. Be sure to update the package descriptions when retrying: `$ sudo apt-get update && sudo apt-get install ros-electric-desktop-full`
2011-10-08 21:57:13 -0500	answered a question	Ubuntu Lucid, cannot install ROS electric I guess we just need some more patient and *wait until the repository is stable*.
2011-10-08 21:55:59 -0500	commented answer	Ubuntu Lucid, cannot install ROS electric I think you are right. the repository were "in a invalid state". Just now I tried it again and it works now. Great. Thanks.
2011-10-08 21:46:27 -0500	commented answer	Ubuntu Lucid, cannot install ROS electric not really. the error message are different. mine starts from missing ros_tutorial; his error msg. starts from electric-eigen; and I don't have libpcl-1.1 libeigen3-dev packages installed at all. but thanks anyway.
2011-10-08 08:42:58 -0500	commented answer	Ubuntu Lucid, cannot install ROS electric I installed Ubuntu 2 days ago. so it is really a clean OS.
2011-10-08 08:41:10 -0500	commented answer	Ubuntu Lucid, cannot install ROS electric now, i.e., 8 hours later, I still get the same error. Is it possible that in my system some packages are missing?
