[Bug 1943614] [NEW] ubuntu-drivers crashes due to click when ubiquity runs the Polish language (locale)

[Łukasz Zemczak]

Public bug reported:

[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.

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.

** Affects: ubiquity (Ubuntu)
     Importance: Critical
         Status: New
