>From time to time I get emails like the one below. I don't use samba
actively, it's installed as a dependency with default settings.

The emails tells to install samba-dbg, but I don't see such a package
with apt search.


========================================================

The Samba 'panic action' script, /usr/share/samba/panic-action,
was called for PID 2020 (/usr/sbin/nmbd).

This means there was a problem with the program, such as a segfault.
Below is a backtrace for this process generated with gdb, which shows
the state of the program at the time the error occurred.  The Samba log
files may contain additional information about the problem.

If the problem persists, you are encouraged to first install the
samba-dbg package, which contains the debugging symbols for the Samba
binaries.  Then submit the provided information as a bug report to
Ubuntu by visiting this link:
