Previously, Checkmk could not be installed on SLES 16.0 due to a missing libexslt0 package dependency. On SLES 15.x, libexslt0 was pulled in automatically as a transitive dependency of libxslt1, but SLES 16.0 dropped that implicit dependency. This caused the following error at runtime:

ImportError: libexslt.so.0: cannot open shared object file: No such file or directory

As a workaround for affected installations, the dependency can be installed manually:

zypper install libexslt0

libexslt0 is now declared explicitly, so installations on SLES 16.0 work correctly without manual intervention.
