Hi all, it is maybe a dumb question. I wanted to use rosbag filter, but it returns an error. I traced it back and found out that one of my custom msgs is unicode instead of ascii. Anyhow, found that this problem was fixed in the package genpy since 0.6.9. rosversion genpy shows me that i have installed 0.6.7 in my kinetic. I tried to update via apt-get install but it looks like no new version is avaible. How can i update to 0.6.9 or 10 for my kinetic installation? is there another way instead of building ros from source?

Thank you for any hints!

From status_page/compare_kinetic_melodic.html?q=genpy, it looks like 0.6.9 is only released into Melodic. 0.6.7 is indeed the latest version for Kinetic.

is there another way instead of building ros from source?

you could try just building genpy from source.

No guarantees this will work though, as genpy is a rather low-level dependency for the message generation and introspection infrastructure. It could require to build all dependants of genyp from source as well.

thanks for the answer. very helpful the page. I got confused because 0.6.10. was still in the kinetic-devel branch here: https://github.com/ros/genpy/blob/kin... But there is simply no melodic branch :)

I was hoping for a simple solution. Thanks! for the quick help
