Version-Release number of selected component (if applicable):

Satellite 6.6 snap 1

How reproducible: always


Steps to Reproduce:
1. Install satellite 6.6
2. satellite-change-hostname qe-testing-rhel7.example.com -y -u admin -p changeme

Actual results:
After hostname change is successful, candlepin is down.

Expected results:
Candlepin should not fail.

Additional info:
Comment 4 Evgeni Golov 2019-05-06 15:07:11 UTC 
I can reproduce this. The problem seems to be that the installer does not refresh the Candlepin/Tomcat keystore.
Comment 5 Evgeni Golov 2019-05-06 15:26:47 UTC 
workaround:
rm /etc/candlepin/certs/candlepin-ca.* /etc/candlepin/certs/keystore
satellite-installer
Comment 6 Eric Helms 2019-05-06 16:26:38 UTC 
I think this may need an update in the code that does the change hostname itself. That code attempts to delete certificates to have the installer regenerate them. This is fragile if the installation moves certificates around which we have done in 6.6 in some cases.
