Traceback (most recent call last):
  File "/usr/lib/ubiquity/ubiquity/frontend/kde_ui.py", line 502, in <lambda>
    0, lambda: self.dbfilter.start(auto_process=True))
  File "/usr/lib/ubiquity/ubiquity/filteredcommand.py", line 103, in start
    prep = self.prepare()
  File "/usr/lib/ubiquity/plugins/ubi-prepare.py", line 336, in prepare
    self.ui.set_using_secureboot(True)
AttributeError: 'PageKde' object has no attribute 'set_using_secureboot'
