Investigation
Step 1 - Verify Package State
The ucs@school app packages seems to be installed as the packages are installed. Check especially for ucs-school-slave package:
root@lenaedu:/# dpkg -l| grep ii| grep ucs-school
ii python-ucs-school 12.1.1-6A~4.4.0.201905061453 all UCS@school - common Python modules
ii shell-ucs-school 12.1.1-6A~4.4.0.201905061453 all UCS@school - common shell functions
ii ucs-school-branding 8.0.0-0A~4.4.0.201902111516 all UCS@school - branding for UMC frontend
ii ucs-school-info 9.0.0-0A~4.4.0.201902111517 all UCS@school: provides info script

If the packages do not appear as installed try installing by univention-app install ucsschool. If this does not succeed, proceed with the next step.
Step 2 - Check App Registration
See if the installed packages are properly registered as Univention ucs@school-app:
Here you notice univention-app info tells us ucsschool is not installed:
root@lenaedu:/# univention-app info
UCS: 4.4-0 errata109
Installed: cups=2.2.1 samba4=4.10 squid=3.5
Upgradable:
So we have a mismatch. All packages are installed but univention-app still tells the app is not installed.
Step 3 - Try to Install Manually
Trying to install the app manually fails, too:
root@lenaedu:/# univention-app install ucsschool
usage: univention-app install [-h] [--noninteractive] [--username USERNAME]
[--pwdfile PWDFILE]
[--set KEY=VALUE [KEY=VALUE ...]] [--dry-run]
[--do-not-revert] [--only-master-packages]
[--do-not-install-master-packages-remotely]
[--do-not-pull-image]
app
univention-app install: error: Unable to find app ucsschool. Maybe "/usr/bin/univention-app update" to get the latest list of applications?
Solution
Step 1
Update the locally stored list of apps with univention-app update.
root@lenaedu:/# univention-app update

Step 2
Check if the ucsschool app appears as installed after updating the app list:
root@lenaedu:/# univention-app info
UCS: 4.4-0 errata109
Installed: cups=2.2.1 samba4=4.10 squid=3.5 ucsschool=4.4 v2
Upgradable:
Step 3
Run join scripts again as they should succeed.
root@lenaedu:/# univention-run-join-scripts
univention-run-join-scripts: runs all join scripts existing on local computer.
