Description Felix Botner univentionstaff 2016-11-30 16:47:37 CET
UCS 4.1 with old UCC app. (App) Update has been started with univention-upgrade. In the meantime the UMC Appcenter has been opened. 

This triggers the appcenter.register code. UMC Appcenter -> appcenter.register checks the packages status of the default packages. The UCC packages where != "ii" (some update status) and the the appcenter removed the app registration (e.g. the component).

20751 is the univention-upgrade process

 20751 actions.upgrade                  16-11-30 14:55:59 [    INFO]: Ersatz für ucc-umc-setup wird entpackt .

UMC appcenter is started, this process removes ucc

 ps aux| grep 22901
root      8910  0.0  0.0   9916  2040 pts/2    S+   16:15   0:00 grep 22901
root     22901  0.3  2.0 464356 81668 ?        S    14:55   0:14 /usr/bin/python2.7 /usr/sbin/univention-management-console-module -m appcenter

 22901 actions.update                   16-11-30 14:55:59 [   DEBUG]: Calling update
 22901 actions.register                 16-11-30 14:56:03 [   DEBUG]: Removing repository/online/component/ucc_20160811170611

After that the packages are correctly updated by 20751.

 20751 actions.upgrade                  16-11-30 14:56:11 [    INFO]: ucc-umc-images (5.0.0-1.14.201605311646) wird eingerichtet .

A UMC Appcenter reopen or univention-app register does NOT (re) register the UCC app!
From now on the AppCenter thinks that this app is not installed.

Comment 2 Dirk Wiesenthal univentionstaff 2017-07-27 13:25:00 CEST
Fixed in
  univention-appcenter 6.0.8-17A~

by checking the installation status of Debian packages not too strictly. So that they should be regarded as installed during a "apt-get dist-upgrade" (App upgrade via App Center or Release Update via Software Update module)
Comment 3 Felix Botner univentionstaff 2017-08-03 17:26:29 CEST
OK - univention-appcenter
