Unfortunately not. This just shows that there was a segfault, but not where and why. With a backtrace there is a much better chance to find the root cause (but even then, it will most likely be hard to figure out) Do you by chance still have a core file of the crash? > It reports the origin of the segfault is libc 2.28, which was upgraded > from 2.27 behind systemd's back: > > -libc-bin 2.27-8 amd64 > -libc-dev-bin 2.27-8 amd64 > -libc-l10n 2.27-8 all > -libc6 2.27-8 amd64 > -libc6-dbg 2.27-8 amd64 > -libc6-dev 2.27-8 amd64 > -libc6-dev-i386 2.27-8 amd64 > -libc6-dev-x32 2.27-8 amd64 > -libc6-i386 2.27-8 amd64 > -libc6-x32 2.27-8 amd64 > +libc-bin 2.28-2 amd64 > +libc-dev-bin 2.28-2 amd64 > +libc-l10n 2.28-2 all > +libc6 2.28-2 amd64 > +libc6-dbg 2.28-2 amd64 > +libc6-dev 2.28-2 amd64 > +libc6-dev-i386 2.28-2 amd64 > +libc6-dev-x32 2.28-2 amd64 > +libc6-i386 2.28-2 amd64 > +libc6-x32 2.28-2 amd64 > > There could have been a daemon-reexec too, at some point. I don't > recall. I haven't seen a segfault in a very long time and you are the first one reporting one wrt the libc6 update. Which I suspect makes it hard to reproduce this issue. Do you by chance have a backup of the system from before the upgrade, which you could restore into a test system and re-run the upgrade?
