Package: samba
Version: 2:4.17.12+dfsg-0+deb12u1
Severity: normal
Dear Maintainer,
* What led up to the situation?
a reboot changed the name of the interface, then it took me a while
to notice that samba wasn't up.
when investigating, i discovered that a wrong interface name
segfaults samba, there is a mail with a stacktrace:

if I change the interfaces = line to the correct interface name no crash

also, the mail refers to the samba-dbgsym package, which does not
exist for me:
If the problem persists, you are encouraged to first install the
samba-dbgsym package, which contains the debugging symbols for the
Samba binaries. Then submit the provided information as a bug report to

Changes:
samba (2:4.22.3+dfsg-3) unstable; urgency=medium
.
[ Sascha Lucas ]
* winbind pam-config: fix account section to actually execute pam_winbind
entries after usually successful cal to pam_unix, in a way how it's done
in sssd (Closes: #907318)
.
[ Douglas Bagnall ]
* debian/panic-action: make the wording more user-friendly and steer users
towards configuration and logs (Closes: #1089853)
.
[ Michael Tokarev ]
* d/python3-talloc.symbols.in: add forgotten epoch number for recent versions
(this doesn't actually affect anything since there were no new symbols with
these versions, but it's better to stay correct)
* d/control: fix winbind:Enhances for libkrb5-26-heimdal which
is libkrb5-26t64-heimdal in trixie and up, keeping in mind possible
backporting to older debian/ubuntu versions (before-trixie build profile)
* libads-fix-get_kdc_ip_string.patch (upstream fix for #1109005)
(Closes: #1109005)
