apt-get dependency problems with alternative package
the thing is, I needed a package to run opera plugins (openmotif). I got this package from the net, but it depends on another package (xlib6g). This package is not available, but apt-get mentions some alternatives. I have installed one of them, and then openmotif. My opera plugins work just fine, so problem solved.
Now apt-get mentions the missing dependency of xlib6g every time I try to use it. Apparently, an alternative is no solution for the dependency. So now I want to tell apt-get not to bug me with this, because I have the alternative, and it works just fine. I tried looking in /var/lib/apt/lists/* but I suspect these files are overwritten every time I apt-get update. So if I modified something there, it would be lost then.
How do I solve this?
