Title:
  update-manager crashed with AttributeError in __init__(): module
  'platform' has no attribute 'dist'

Status in update-manager package in Ubuntu:
  Fix Released

Bug description:
  This happened just after installing ubuntu-restricted-extras via
  terminal, though the specific package may be irrelevant. I also
  checked for updates with update-manager, and that's when this error
  appeared. I will also note the same error appeared on another one of
  my focal systems. As for this system, I installed all available
  updates via the terminal, and this error appeared again.
