Bug#1054875: /usr/bin/add-apt-repository: python3-launchpadlib required for apt-add-repository

[Luke W Faraone]

Package: software-properties-common
Version: 0.99.30-4
Severity: normal
File: /usr/bin/add-apt-repository
X-Debbugs-Cc: lfar...@debian.org

Using the apt-add-repository command with a Launchpad PPA produces this
unhelpful error:

$ sudo add-apt-repository ppa:yuezk/globalprotect-openconnect
Traceback (most recent call last):
File "/usr/bin/add-apt-repository", line 362, in <module>
sys.exit(0 if addaptrepo.main() else 1)
^^^^^^^^^^^^^^^^^

shortcut = handler(source, **shortcut_params)

AttributeError: 'NoneType' object has no attribute 'people'

I understand that adding a PPA is not a "supported" operation in Debian, but at
the very least a hint for the needed package should be displayed.
