Hi,
i have many old entries of not installed Apps in my Ldap. I tried to delete the Containers, but after i did this, the Server crashes and dont run again. I needed to restore it.
How i can savely Clean the Ldap Tree?
For example this:
Thanks
Just leave them there. Those entries don’t hurt. It’s just a few bytes in a database. You also don’t need to delete man pages that you don’t read. They are just a few bytes on your hard disk.
And if the system crashes after deleting them - they are required bits.
Generally Univention packages will cleanup their data on disk very well. But in LDAP they often cannot, because it is extremely difficult to safely say, that no other software will use that data anymore. Generally software does not delete user-generated data.
In the above case, the data is part of the Univention Appcenter. The Appcenter keeps track of previously installed software, so that restored backups can be more useful. If LDAP nodes are not used, they don’t hurt the performance. But as you have experienced (with the crash): the data is actually used. So please leave it be.
Greetings
Daniel
I agree to leaving them there for the reasons you mentioned.
I disagree to the comparison to man pages, though. With man pages you generally don’t look at the index of man pages. Here you even have a LDAP tree viewer integrated into UCS. Having many old items increases confusion when solving problems - this is not only a problem with LDAP.

The Problem is, if i install a new Server with Portal, i ever have Rocketchat Links and some more, but the apps are not installed.
Nextcloud, Element, Wekan and Rocket.chat are not installes on any Server:
Its very annoying and confusing user, they come on the portal via load balancer and every time other links are there
Thanks

@Andreas_T you are right - stale data is annoying, when searching.
@Corin that’s bad. Please try the following: install rocketchat on some system and uninstall it. See if it fixes the entry. You can install a specific version on the command line. First list available version:
univention-app list rocketchat
univention-app install rocketchat=3.15.1
univention-app remove rocketchat

It works. Now the ldap is free of Rocketchat Data. May i do this with all old Apps? Wekan, Etherpad, Nextcloud?
Thanks
Btw: what is shown, when you execute univention-app info ?
May i do this with all old Apps?
Well… it’s not elegant, but it works…
