We already had some thousand RHEL-hosts running with Katello repositories/contentviews/activationskeys and moved some hundred SLES-VMs from SUSE Manager 3.2 to Katello 3.14 in 2020 successfully but with some problems still remaining:
- “Could not calculate errata status, ensure host is registered and the katello-host-tools package is installed (Errata)” – both SLES12 and SLES15
- “System Purpose = Mismatched” – only SLES12
- Katello served repos can not completely be enabled on SLES-VMs - therefore we manage the repos with a simple puppet template file instead of using an actication-key with the repos needed for SLES12SPx or SLES15SPy - have a look at: Entitlement certificate not containing all content (…SLES systems not getting all their repositories…)
