Comment 1 for bug 1258112

That's creating https://errors.ubuntu.com/problem/3ca9b88401b3789ff4d00462be7b20206f60e181 for apturl

way to reproduce
- call apturl-gtk apt:<somebinarynotinstalled
- click install
- when the password prompt shows, hit "esc" on the keyboard

you get the stacktrace

"Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/defer/__init__.py", line 483, in _inline_callbacks
