Hello,

I got segmentation fault error but I don't know where it is. Anyone familiar with this error? I don't know what to write so if you need more information, I will update the info here. Thank you.

First thing to check is whether you have done any partial upgrades. There is no ABI (bw) compatibility guarantee right now for ROS .deb packages, so if you do a partial upgrade (ie: only a subset of available packages get updated), you can run into these sort of problems.

Another potential cause: upgrades of dependencies that were/are not ABI bw compatible. That would be a violation of Ubuntu/Debian policy, but it does happen.

Third potential cause: you updated ROS .deb packages (using apt or the software centre, or even a from-source build), but haven't rebuilt your workspace. Again, due to no-ABI-bw-compatibility guarantee, workspaces must be rebuilt after upgrading packages.

Hmm, I am working in a RasPi ina team so I am not really understand whether it has previously updated or not. Can you explain what does it relate to this segfault error? Thank you.
