Description Dirk Wiesenthal univentionstaff 2017-06-01 11:53:45 CEST
When ucsschool="4.1 R2 v11" was installed and an update is made,

  univention-app register ucsschool
tries to register the 4.1 App again.

This will eventually lead to an unregistered component.

Workaround here:
  univention-app register 4.2/ucsschool="4.2 v1" --do-it
Comment 1 Dirk Wiesenthal univentionstaff 2017-06-12 17:47:29 CEST
Fixed in
  univention-appcenter 6.0.7-19A~

You can test it with
  univention-app get $app ucs_version

But the App may not have been registered correctly, yet the packages of $app have to be installed and the component has to be included. The component requisite does not hold for UCS components (they have WithoutComponent=True)

So the easiest way to test:
apt-get install univention-dhcp
univention-app get dhcp-server ucs_version
Comment 2 Felix Botner univentionstaff 2017-06-14 11:36:23 CEST
OK - univention-appcenter get $APP ucs_version
