What do you think an strace is going to tell us? Please Install gdb and debug symbols for apt, libstdc++6, libc6, and produce a backtrace. So libapt-pkg5.0-dbgsym, libstdc++6-dbgsym, libc6-dbgsym at a minimum. You might want to install systemd-coredump so that cores are always dumped and stored and you can then analyze them with coredumpctl gdb and get a backtrace there to send in bug report. You probably want to configure gdb to log to a file and get a full backtrace, then attach that file, e.g. $ gdb --args apt upgrade set logging overwrite on set logging file /tmp/apt-crash.log set logging on set pagination 0 run backtrace full quit $ ... attach /tmp/apt-crash.log to bug report ... The same thing without the run if you used coredumpctl gdb, because, um, you are analysing a prior crash rather than making it crash again :) -- debian developer - deb.li/jak | jak-linux.org - free software dev ubuntu core developer i speak de, en
