[Bug 1827441] Re: ubuntu-release-upgrader crashed with configparser.NoOptionError: No option 'devrelease' in section: 'Options'

[Brian Murray]

Here's the relevant part of the Traceback:

Traceback (most recent call last):
  File "/usr/lib/python3.6/configparser.py", line 789, in get
    value = d[option]
  File "/usr/lib/python3.6/collections/__init__.py", line 883, in __getitem__
    return self.__missing__(key)            # support subclasses that define __missing__
  File "/usr/lib/python3.6/collections/__init__.py", line 875, in __missing__
    raise KeyError(key)
KeyError: 'devrelease'

During handling of the above exception, another exception occurred:
