Description Ingo Steuwer

UCS 4.1-4 DC Slave, Errata status of week 15/2017

The system had various apps installed successfully, including docker based apps (owncloud, etherpad, nextcloud). While trying to migrate the horde app to docker following http://wiki.univention.de/index.php?title=Horde_App_Migration, the first attempt to install the docker version of the app failed.

Command was "univention-app install horde"

I called "univention-app install horde" a second time and the app was installed successfully.
