Can you please open a terminal, and run /usr/lib/ubuntu-sso-client/ubuntu-sso-login manually inside the terminal, pasting the resulting output here, if there is any? Thanks.

[Michael Donux (chddx-nux-deactivatedaccount)]

Sure, here is the output when I ran the command.

Traceback (most recent call last):
  File "/usr/lib/ubuntu-sso-client/ubuntu-sso-login", line 63, in <module>
    from ubuntu_sso.main import main
ImportError: No module named ubuntu_sso.main
