failed to rename rospack cache
I am running the AR drone drivers and teleop package from Brown University's repository and I keep getting this error when I run the driver:
[rospack] Error: failed to rename cache file /home/ubuntu/.ros/.rospack_cache.SBalWf to /home/ubuntu/.ros/rospack_cache: No such file or directory
This error started showing up recently as it was running earlier. I am running Ubuntu 11.04 off a USB stick which has about 200MB of free space remaining. I was wondering if this was due to space running low on the disk, not sure. Looked around for help but could not find this error posted online. Any help would be appreciated.
