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

[Jean-Baptiste Lallement]

I think it's a due to this commit

commit 656fd91bc7f785982fed89ab70e1d1a686f5e8d4

    prepare: Detect whether there are OEM enablement package for the system
    
    Record this so that it can be used later on when actually installing.
    
    Installation can be disabled by preseeding ubiquity/install_oem.

Title:
  Ubiquity crashes during Kubuntu install on WIFI menu

Status in ubiquity package in Ubuntu:
  Triaged

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.
