process for getting dbgsym packages updated

[Mike Kupfer <mkupfer@alum.berkeley.edu>]

On Debian 11.3, I've discovered that I can reliably get a core file from
/usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitWebProcess by using Atril
to view a PDF file (any PDF file that I've tried).  But the dbgsym
packages for libwebkit2gtk-4.0-37 and libjavascriptcoregtk-4.0-18
(version 2.34.6-1~deb11u1) do not match the installed libraries (version
2.36.0-3~deb11u1).

Is there a process for getting the dbgsym packages updated?

thanks,
mike
