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 ** Attachment added: "Script to demonstrate problem" https://bugs.launchpad.net/ubuntu/+source/wajig/+bug/892410/+attachment/3017471/+files/wajsim -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/892410 Title: Wajig displays incorrect new and upgradeable package count To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/wajig/+bug/892410/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
