Hi David,

Coming back to this problem now that I have a bit more time.

As I have been making a lot of testing, this message is a bit long,
sorry for that.


>If you follow my recipe, any packages counted twice (as eg in both
>the stable and jessie searches) will show up in the diff with a "-".

I have done this first for a = [trusty,jessie$,jessie-backports,stable]
and then for a = now. No output for jessie$.

Then I have done this:

cat jessie-backports.txt trusty.txt stable.txt | sort | diff -u -now.txt > diff.txt

The first lines of diff.txt show

Now, for example, we see that autopoint is present twice (once with a
"-" and once with a blank space at the beginning of the line). So if I
understand correctly, the package "autopoint" appears once in both the
concatenation and in the total file and another time only in the
concatenation. Can I see this behaviour using apt-cache?

apt-cache policy autopoint 
autopoint:
  Installé : 0.19.3-2
  Candidat : 0.19.3-2
 Table de version :
     0.19.8.1-1~bpo8+1 0
        100 http://ftp.ch.debian.org/debian/ jessie-backports/main amd64 Packages
 *** 0.19.3-2 0
        500 http://ftp.ch.debian.org/debian/ jessie/main amd64 Packages
        100 /var/lib/dpkg/status


So it seems that it's the jessie version which is installed. But

aptitude search ~Astable~i | grep autopoint
i A autopoint

aptitude search ~Ajessie$~i | grep autopoint
(no output)

aptitude search ~Ajessie-backports~i | grep autopoint
i A autopoint


which contradicts apt-cache! Is this a bug? Same behaviour for the
package cmake-data.


(BTW, this package is taken from jessie but there is an existing
backport package. Is is possible to upgrade to jessie-backports all
jessie packages which have a jessie-backports version?)

The packages with a starting "+" are the obsolete ones.

Ok thanks :-)

Best,
