[Xapian-discuss] trouble on getting source

[Allen]

I have a problem on getting source of xapian.

1st, run 'wget -O- http://www.xapian.org/debian/archive_key.asc|apt-key add
-', result shows '09:35:29 (6.42 KB/s) - `-' saved [2437/2437]' and OK, but
i found nothing on my disk,

2nd, run 'apt-get update' but get a warnning:
W: Conflicting distribution: http://www.xapian.org stable Release (expected
stable but got etch)
If it caused by the 1st step?

I modify my /etc/apt/sources.list, from stable to unstable:
deb http://www.xapian.org/debian unstable main
deb-src http://www.xapian.org/debian unstable main

run 'apt-get update' but get another warnning:
W: Conflicting distribution: http://www.xapian.org unstable Release
(expected unstable but got sid)
