I want core dumps for my crashing application, but can't find them. According to this answer I should be using apport.

$> systemctl list-unit-files | grep apport                                                                                                                                           
apport-autoreport.path                     enabled        
apport-autoreport.service                  static         
apport-forward@.service                    static         
apport.service                             generated      
apport-forward.socket                      enabled

Looks okay, right?

$> cat /proc/sys/kernel/core_pattern
|/usr/share/apport/apport %p %s %c %d %P

But I don't see any core files in my current directory or /var/crash.

I also tried

$> sudo sysctl -w kernel.core_pattern=core.%u.%p.%t
$> cat /proc/sys/kernel/core_pattern
core.%u.%p.%t

I still don't see any core files being created.

What am I missing?

Have you solved this problem? rewrite core_pattern file can solve the paoblem,like echo "/var/crash/core.%u.%E.%p" > /proc/sys/kernel/core_pattern. but i don't want rewrite core_pattern file.
