I tried "sudo apt-get install --reinstall gnome-software" in case something was lost when upgrading to Ubuntu 20.04. Afterwards when I ran gnome-software, it said '"GNOME Software" needs to be restarted to use new plugins' but when I clicked "Restart Now", it hung.
This time syslog had these lines: Jul 5 18:01:21 lxjima systemd: tracker-store.service: Succeeded.
