I installed ros groovy recently, and now I got this error frequently when I use command "roscore":

After a system reboot, I can launch it successfully. Please help! Thank you in advance.

Solved this with

sudo pip install --upgrade netifaces

(Similar to Jochen's answer above, this upgrades python netifaces.)

I've had the same problem on Ubuntu 12.04 and fixed it by installing python-netifaces from 12.10.

I had the same problem but I already installed python-netifaces from 12.04. But I still got the same question. How did you install python-netifaces from 12.10?

I have the same error in my application. I am using CAN (Controller Area Network) interface with peak system. When I try to use only the roscore command with the peak connected on the USB port it give the same error: "You must specify a valid interface name." On the other hand, when I run roscore without connecting the peak system, it seems to be okay.

I saw this post https://github.com/ros/ros_comm/pull/211 but didn't help.

Any other ideas how it could be solved?
