Comment 43 for bug 994921

I think it might be possible for any user to see their own automatic crash reports, but the process is a little obfuscated.

If you're using Unity then you can open:

System Settings >
 Security & Privacy >
 Diagnostics >
 Show Previous Reports

But I can't find any such option in gnome-control-center or 18.04. So you then have to make the link yourself:

  https://errors.ubuntu.com/user/ID

where ID is the contents of /var/lib/whoopsie/whoopsie-id

So you can try running this command to open it:

  xdg-open https://errors.ubuntu.com/user/`sudo cat /var/lib/whoopsie/whoopsie-id`
