Comment 2 for bug 892410

I can reproduce it. The problem (in my case, anyway) is due to the fact that a package might be available from more than one source, and wajig is including all these in its calculation, while only one version of a package can be installed, of course.

I've written a bash script to simulate "wajig update", which I'm attaching. It doesn't issue "apt-get update", but works with the current apt and dpkg files. Then instead of displaying a count, it displays the problematical packages. It doesn't need root. When I run the script, I get:

bash wajsim
libmysqlclient16 5.1.61-0ubuntu0.11.10.1 5.1.58-1ubuntu5 5.1.61-0ubuntu0.11.10.1
