Hello Łukasz, or anyone else affected,

Accepted ubuntu-drivers-common into bionic-proposed. The package will
build now and be available at
https://launchpad.net/ubuntu/+source/ubuntu-drivers-
common/1:0.8.6.3~0.18.04.2 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in

Bug description:
  [Impact]

  Ok, first of all - I am unsure if this is a regression or not, since I did not test extra drivers with old images. I'm testing this on kvm now.
  So far this bug appeared for me when I was running ubiquity with secureboot enabled on a NVidia GPU machine.
  Note: this only happens when the language selection is done on the Ubiquity screen. If you get the language right in the isolinux menu, everything works.

  Basically when installing Ubuntu desktop on a system that uses ubuntu-
  drivers but using a non-standard locale (like in my case, the Polish
  language from the language selector), ubuntu-drivers will crash with:

  `
  Traceback (most recent call last):
    File "/usr/bin/ubuntu-drivers", line 480, in <module>
      greet()
    File "/usr/lib/python3/dist-packages/click/core.py", line 722, in __call__
      return self.main(*args, **kwargs)
    File "/usr/lib/python3/dist-packages/click/core.py", line 676, in main
      _verify_python3_env()
    File "/usr/lib/python3/dist-packages/click/_unicodefun.py", line 118, in _verify_python3_env
      'for mitigation steps.' + extra)
  RuntimeError: Click will abort further execution because Python 3 was configured to use ASCII as encoding for the environment.  Consult http://click.pocoo.org/python3/for mitigation steps.

  This system supports the C.UTF-8 locale which is recommended.
  You might be able to resolve your issue by exporting the
  following environment variables:

      export LC_ALL=C.UTF-8
      export LANG=C.UTF-8

  Click discovered that you exported a UTF-8 locale
  but the locale system could not pick up from it because
  it does not exist.  The exported locale is "pl_PL.UTF-8" but it
  is not supported
  ubuntu-drivers autoinstall failed with code: 1
  `

  [Test Case]

  * Download latest 18.04.6 candidate image for ubuntu-desktop
  * In language selector, select Polish (Polski)
  * Proceed with the installation and checking "Install third-party software..."
  * Boot into the installed system
  * Check if `ubuntu-drivers install ...` succeeded during installation, checking the installer syslog.
