How to get the symbol package?

My process got a segmentfault, and the back trace : 0x00007f3a8405c72e in mongoc_stream_destroy () from /lib/x86_64-linux-gnu/
How can I get the debug package?
Version: libmongoc-1.0-0/stable,now 1.17.6-1 amd64
OS: debian-11

You need to install the debugging symbols using one of the methods described in the HowToGetABacktrace Debian wiki article.
