Qlik Replicate currently supports the majority of RHEL-based operating systems, but does not appear to support ubuntu. Our enterprise direction for linux flavors is to use AlmaLinux8 or Ubuntu, and while AL8 is compatible for replicate, it does not support DB2 components at this time. Our organization has heavy use for db2 z/OS, and there's no telling when AL8 will support DB2 linux components. Ubuntu is an open-source OS that doesn't have additional costs associated to it (unlike RHEL8), and we believe this OS will be used more within large companies.
