Apps/Packages which bring UCR Templates or LDAP-Schema/LDAP-Extensions using Python blocks may cause the upgrade to fail by preventing a slapd start.

We should detect such cases in the preup.sh/check.sh and block the update accordingly.
A python syntax check should be done.

One example was:

Multifile: /etc/ldap/slapd.conf
  File "<stdin>", line 11
    print 'include        /usr/share/univention-ldap/schema/oxforucs-extra.schema'
                                                                                 ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print('include        /usr/share/univention-ldap/schema/oxforucs-extra.schema')?
  File "<stdin>", line 18
    ''' % { 'access' : access }
      ^
SyntaxError: invalid syntax
