[rosrun] Couldn't find executable named _shim below /opt/ros/melodic/share/rosmon_core #91

Closed matawed closed 4 years ago

matawed commented 5 years ago

After upgrading to 2.1.0-1 on Ubuntu 18.04 and launching a previously running launch file now fails. All nodes crash with the following error message:

[rosrun] Couldn't find executable named _shim below /opt/ros/melodic/share/rosmon_core
node: node exited with status 3

whereas the same launch file runs fine with roslaunch.

Was there some error during packaging? Seems that this executable is missing.

dpkg -L ros-melodic-rosmon-core yields:

Urgh, that was not supposed to happen (and I was supposed to test the built package before the melodic sync happened -.-). Thanks for reporting!

I'll push a new patch release shortly.

This is one of the possible mistakes that currently slip through the CI pipeline and requires manual testing of the binary packages that are built by the ROS buildfarm. Somehow I messed up my timing this release cycle and didn't do that step. I apologize to everyone affected.

If you need a fix/workaround now, you can:

@xqms Where could we find the packages built by the buildfarm? I am not very familiar with the ROS buildfarm. Thank you.

xqms commented 5 years ago

@romainreignier You can either switch your apt sources to the "shadow" repository, which will automatically give you the released versions even before the sync happens. I would not recommend this on your usual developer or even production machine. Although using it greatly helps package maintainers because hopefully bugs like this one can be caught before they hit the official repo.

The other possibility is to download the rosmon packages manually from the repository, and install/update only these:

http://repositories.ros.org/ubuntu/testing/pool/main/r/ros-melodic-rosmon-core/ros-melodic-rosmon-core_2.1.1-1bionic.20190709.214808_amd64.deb http://repositories.ros.org/ubuntu/testing/pool/main/r/ros-melodic-rosmon-msgs/ros-melodic-rosmon-msgs_2.1.1-1bionic.20190709.213006_amd64.deb http://repositories.ros.org/ubuntu/testing/pool/main/r/ros-melodic-rosmon/ros-melodic-rosmon_2.1.1-1bionic.20190709.215647_amd64.deb http://repositories.ros.org/ubuntu/testing/pool/main/r/ros-melodic-rqt-rosmon/ros-melodic-rqt-rosmon_2.1.1-1bionic.20190709.214533_amd64.deb

Install the downloaded .deb files all at once with sudo dpkg -i <files...>.

This procedure is only required for ROS Melodic, ROS Kinetic already has the fixed version synced.

The fixed versions have been in the repositories for quite a while now, closing.
