Package 'oda-hw-mgmt' isn't signed with proper key

I just upgraded an ODA X7-2M from 18.8 to 19.6.

When I sudo to root following the upgrade I got the following message :

ABRT has detected 2 problem(s). For more info run: abrt-cli list --since 1602931468

When I check /var/log/messages I can see following lines from abrt-server

[root@xxx log]# grep abrt messages
