[Bug 1869992] Re: Ubiquity crashes during Kubuntu OEM install on WIFI menu

[Darin Miller]

grepping all files in the ubiquity package for frontend.ubuntu_drivers
shows the only reference is in ubi-prepare.py.  I suspect code was
removed from one of import files, but I do not know how to use LP well
enough to discover the offending commit.

Title:
  Ubiquity crashes during Kubuntu OEM install on WIFI menu

Status in ubiquity package in Ubuntu:
  New

Bug description:
  Kubuntu OEM install crashes after attempting to pass the Wireless menu
  during install.  Crash occurs regardless if user chooses to connect to
  wifi. Text from the Installer crashed window:

  Traceback (most recent call last):
    File "/usr/lib/ubiquity/ubiquity/frontend/kde_ui.py", line 514, 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 419, in prepare
      if self.frontend.ubuntu_drivers:
  AttributeError: 'Wizard' object has no attribute 'ubuntu_drivers'

  Checking apt list in the terminal shows:
     ubuntu-drivers-common/focal,now 1:0.8 amd64 [installed,automatic]

  So I suspect a script init issue.
