Hi
I updated my UCS Core Edition from 4.4 to 5.0, it works without problems. After this i would upgrade to the last version but i got this message:
Checking required_ucsschool_version … Traceback (most recent call last):
File “”, line 7, in
AttributeError: ‘NoneType’ object has no attribute ‘is_installed’
FAIL
Checking role_package_removed … OK
Checking slapd_on_member … OK
Checking ssh … OK
Checking system_date_too_old … OK
Checking term … OK

The system can not be updated to UCS 5.0 due to the following reasons:
required_ucsschool_version:
UCS@school is installed. To upgrade to UCS 5.0-2 as least UCS@school 5.0 v2 is required.
Please upgrade the UCS@school app first!
Error: Update aborted by pre-update script of release 5.0-2
How can i change to my former Edition back?
I dont use UCS@School! I use “UCS Core Edition”.
There isnt any school app in my installation.
Idont understand this, but in my testinstallation there is the same test!
