Comment 24 for bug 1579834

@ thorsten-1

A good way to find out such is to look at Launchpad

https://launchpad.net/ubuntu/+source/apt-xapian-index

Any Release/Version is listed there – use the arrows to exand the view.

You can just simply countercheck your installation (via konsole/command-line):

dpkg-query -l *xapian*

or if you know already the exact package name:

dpkg-query -l apt-xapian-index
