[Bug 1669649] Re: update-apt-xapian-index crashes with IndexError: list index out of range

[Simon Quigley]

Marking as Invalid because the release is EOL is not correct. Marking as Incomplete. Also, 18.04 is (at the time of writing) still in development, and you should expect some breakage.
https://wiki.ubuntu.com/Bugs/Responses#Release_has_reached_End_of_Life_.28EOL.29

Reporter, is this still present on 17.10 or 16.04?

** Changed in: apt-xapian-index (Ubuntu)
       Status: Invalid => Incomplete
