Bug#672770: gnuplot: Unable to upgrade gnuplot-nox or gnuplot-x11

[Paul Menzel]

Package: gnuplot
Version: 4.6.0-8
Severity: normal

Dear Debian community,


I am unable to upgrade the packages `gnuplot-nox` and `gnuplot-x11`.

        $ LANG=C aptitude -s install gnuplot-nox gnuplot-x11 # still 4.6.0-5
        The following packages will be upgraded: 
          gnuplot-nox{b} gnuplot-x11{b} 
        2 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
        Need to get 1988 kB of archives. After unpacking 689 kB will be used.
        The following packages have unmet dependencies:
         gnuplot-x11 : Conflicts: gnuplot-nox but 4.6.0-8 is to be installed.
         gnuplot-nox : Conflicts: gnuplot-x11 but 4.6.0-8 is to be installed.
        The following actions will resolve these dependencies:

             Remove the following packages:
        1)     gnuplot-nox                 



        Accept this solution? [Y/n/q/?] q
        Abandoning all efforts to resolve these dependencies.
        Abort.

This seems to be related to a change in 4.6.0-6.

        gnuplot (4.6.0-6) unstable; urgency=low

          * [2c1a288] Change Replaces by Conflicts between different gnuplot-* flavors.

        […]

I do not know the reason for these conflicts, but somehow the upgrade
path got broken. I think Conflicts, Breaks and Replaces all have to be
set somehow to hint the package manager how to proceed.

I thought bug #671876 [1] would fix it, but I guess this issue is
unreladed.


Thanks,

Paul
