Title:
  add-apt-repository sometimes crashes when SIGINT (Ctrl+C) is sent:
  crashed with ImportError in get_ppa_info_from_lp(): No module named
  'pycurl'

Status in “software-properties” package in Ubuntu:
  New

Bug description:
  It appears add-apt-repository will sometimes crash instead of properly
  terminating, when SIGINT is sent (e.g., by Ctrl_C being pressed).

  This crash happened when I entered a "sudo add-apt-repository ..."
  command with a typo in the name of the PPA I was adding. This crash
  was probably not triggered even partially by special syntax--the typo
  was just a misspelling.

  The expected behavior would be for add-apt-repository not to crash
  when Ctrl+C is pressed (or when SIGINT is otherwise sent). Whether or
  not any substantive cleanup is performed when Ctrl+C is pressed, it
  should be considered a bug for an actual crash to occur in response to
  it. The primary negative impact of this bug on users is probably that,
  on most stable systems, Apport/Whoopsie runs when a crash occurs. But
  even if the crash were silent, it is still a bug.

  With that said, this is unlikely to be a serious bug. Its impact is
  minimal, it does not ever prevent add-apt-repository from being used
  effectively, and add-apt-repository does terminate when Ctrl+C is
  given (it just crashes sometimes while doing so). Furthermore, add-
  apt-repository probably only crashes some of the time--rather than
  every time--that SIGINT is sent.
