How can I view the core dump in 18.04 LTS?

Question

I am experimenting with C-pointers and I get segmentation faults and want to view the core. Following the advice at Where do I find the core dump in ubuntu 16.04LTS? doesn't work for me. Also looked at https://wiki.ubuntu.com/Apport but that is for package developers and I am not writing a package. How can I enable it? Next question is how to work with it, but I can perhaps take that elsewhere

Answer 1

If youu want to enable Apport, run: sudo systemctl enable apport.service to start on every boot or sudo service apport start to start apport only for that session.

Apport itself is running at all times, however, the crash sensing component is still disabled. To enable it permanently, run the command:

sudo nano /etc/apport/crashdb.conf

and add a hash symbol # at the beginning of the following line:

'problem_types': ['Bug', 'Package'],

To disable crash reporting just remove the hash symbol.
