Description of problem:

When using the "Update All Packages" option to install all applicable updates to hosts, those updates install on RHEL 6 and RHEL 7, but they don't install on RHEL 8.  However, the tasks still appear complete successfully.  This can be confirmed by running "yum update" and answering "N" both before and after attempting to update through the web interface.

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

At least Satellite 6.5 and 6.6.


How reproducible:

Consistently.

Steps to Reproduce:
1.  select Hosts > ContentHosts
2.  click the check-mark box next to a host
3.  click on the Action menu
4.  select "Manage Packages"
5.  click "Update All Packages"
6.  click Yes to confirm
7.  click the Done button

Actual results:

The update task completes with no errors, but the number of packages to install on RHEL 8.0 or 8.1 hosts, as reported by running yum update on the host itself, doesn't change as compared to the number of packages reported before running the above steps.

Expected results:

The number of packages to install on RHEL 8 hosts should drop to zero, or the update task on the Satellite side should fail.


Additional info:

The command "yum update" still works, as does this workaround:

1.  select Hosts > ContentHosts
2.  click on the host name
3.  click on the Packages tab
4.  select Applicable
5.  change the drop-down menu from "20" per page to "100" per page
6.  click the check-mark box "Upgradable Package"
7.  click the button "Upgrade Selected"
8.  select 'via Katello agent"
9.  repeat until all applicable packages have been installed
