Hi, I tried installing ROS electric from sources on Debian and I had a failure: [ rosmake ] rosdep install failed: md5sum check on https://kforge.ros.org/rosrelease/viewvc/sourcedeps/assimp/assimp--2.0.863-sdk.tarfailed. Expected 2ed0b9954bcb2572c0dade8f849b9260 got bda6c1c3a70657cfa1bca6c3e5384639 Is the checksum outdated?
