Unfortunately, with more than four devices the wizard hangs again.
 

+++ This bug was initially created as a clone of Bug #36880 +++

See screeshot for JS exact error, reproducible with two network interfaces where one (in this case eth1) is not configured via UCR.

There were 5 places where a not existing widget was accessed. So I fixed the method which returns the network devices to only return the first 4 widgets.

Package: univention-system-setup
Version: 8.1.65-3.791.201411251527
Branch: ucs_4.0-0
Scope: errata4.0-0

WORKAROUND for affected systems is to execute the following lines on the CLI:
sed -i 's#return devices;#return devices.slice(0, 4);#' /usr/share/univention-management-console-frontend/js/umc/modules/setup/ApplianceWizard.js;
. /usr/share/univention-lib/umc.sh;
umc_frontend_new_hash;

After this a browser reload is necessary.

Works fine now, the fix only shows at maximum 4 network interfaces.
YAML file ok (updated the package version).

→ VERIFIED
