apt-get question

[Rodolfo Medina <rodolfo.medina@gmail.com>]

In order to catch the newer version of opensync, I added to sources.list the
following lines:

 #opensync
 deb http://opensync.gforge.punktart.de/repo/opensync-0.21/ etch main
 deb-src http://opensync.gforge.punktart.de/repo/opensync-0.21/ etch main

and then did: `apt-get update'.  Then I did: `apt-get install libopensync0',
but the system would insist upon installing the older version:

 [...]
 Media Change: Please insert the disc labelled
 ‘Debian GNU/Linux 4.0 r0 _Etch_ - Official i386 DVD Binary-1 20070407-11:40’
 in the drive ‘/cdrom/’ and press enter

How can install what I want, i.e. the newer version from the repository?  I
also tried with `apt-get install libopensync0=0.22' but didn't work.

Thanks for any help
Rodolfo
