Hi all.
I'm using Debian Squeeze.

When I invoke apt-cache policy , for example , apt-cache policy zlib1g,
I get the output like

Code:

zlib1g:

  Installed: 1:1.2.3.4.dfsg-3

  Candidate: 1:1.2.3.4.dfsg-3

  Version table:

 *** 1:1.2.3.4.dfsg-3 0

        500 http://cdn.debian.or.jp/debian/ squeeze/main i386 Packages

        100 /var/lib/dpkg/status

.
And below the line "Version table:" , there is installed package version.
I assume 1:1.2.3.4.dfsg-3 is version("epoch"+"upstream version"+"debian revision"), but what does the next "0" means?
Could someone let me know pls?

The debian wiki on AptPreferences ( http://wiki.debian.org/AptPreferences ) is quite unclear on this subject, but the references section has a link that explains it a bit more

package-name:
Installed: <installed-version>
Candidate: <version-installed-when-doing-apt-get-upgrade>
Package-Pin: <version-of-Pin-in-etc-apt-preferences>
Version table:
*** <some-version> <minimum-priority-to-consider>
<priority-of-this-instance> <repository1>
<priority-of-this-instance> <repository2>
*** <some-other-version> <minimum-priority-to-consider>
<priority-of-this-instance> <repository3>
<priority-of-this-instance> <repository4>

It would be the <minimum-priority-to-consider> to be a candidate for installation
