The location of the coredump file depends on your system configuration.
Please, check "cat /proc/sys/kernel/core_pattern"
If you have systemd-coredump in the output of the above command, then likely the
location of the coredump files is "/var/lib/systemd/coredump/"
You can also change the location of where your system places the coredump files:
echo '/PATH_TO_YOU_LOCATION/core_%e.%p' | sudo tee /proc/sys/kernel/core_pattern
See if that helps...
