I also tried adding the deb-src repositories (for my sources.list which has bionic/bionic-updates/bionic-security with main/universe/multiverse), then attempted to use apport-retrace [1] with a sandbox to download symbols automatically, but log file didn't have sufficient fields:
> ubuntu@ubuntu:~$ apport-retrace -S ~/temp_apport/ /var/crash/_usr_bin_nm-connection-editor.999.crash
> ERROR: report file does not contain one of the required fields: Package
