SUSE Manager 4.0 is based on SLES 15 SP1 as the host operating system. SUSE Manager comes with a maintenance lifecycle of two years. For more information, see https://www.suse.com/lifecycle/.

Long Term Service Pack Support (LTSS) for 15 cannot be added to SUSE Manager. It is also not possible to use SLES for SAP as a base for SUSE Manager to increase the lifecycle of the underlying operating system.

Direct link to SUSE Linux Enterprise 15 SP1, required to install SUSE Manager 4.0: https://download.suse.com/index.jsp?product_id=&search=Search&families=22609&version=68287. With the Unified Installer you can install many SLE-based base products such as SLES, SLES for SAP Applications, or SUSE Manager.

Supported Browsers for the SUSE Manager Web UI

In order to use the Web UI to manage your SUSE Manager environment, you will need to ensure you are running an up to date web browser.

SUSE Manager is supported on:

  • Latest Firefox browser shipped with SLES

  • Latest Chrome browser on all operating systems

  • Latest Edge browser shipped with Windows

Windows Internet Explorer is not supported. The SUSE Manager Web UI will not render correctly under Windows Internet Explorer.

Partition Permissions

When you create disk partitions for the SUSE Manager Server and Proxy, ensure you set the permissions correctly.

For /var/lib/pgsql:

  • Owner: Read, Write, Execute

  • Group: Read, Execute

  • User: None

For /var/spacewalk:

  • Owner: Read, Write, Execute

  • Group: Read, Write, Execute

  • User: Read, Execute

Check the permissions with this command:

ls -l /var/lib/pgsql /var/spacewalk

The output should look like this:

drwxr-x--- 1 postgres postgres /var/lib/pgsql
drwxrwxr-x 1 wwwrun   www      /var/spacewalk

If required, change the permissions with these commands:

chmod 750 /var/lib/pgsql
chmod 775 /var/spacewalk

And owners with:

chown postgres:postgres /var/lib/pgsql
chown wwwrun:www /var/spacewalk
