System updates tool from the UI shows no new updates, apt-get update and apt-get upgrade, show no newer version.
I performed the steps:
ucr set locale="$(sed -ne "s/locales='(.*)'/\1/p" </etc/univention/installation_profile)"
ucr set locale/default="$(sed -ne "s/locale_default='(.*)'/\1/p" </etc/univention/installation_profile)"
and the behavior is now slightly different in that I don't see the greyed out info in the background any longer on the basic tab, just a blank white screen with the busy widget.
[color=#FF0000]EDIT:[/color] after rebooting the Basic setting tab operates as expected.
[color=#FF0000]EDIT2: [/color] after applying changes to network settings the behavior returned to busy pointer as shown in my first post. another reboot results in basic settings showing blank with busy pointer again.
