update-manager in Ubuntu 9.04 doesn't check for duplicated entries in sources.list

[Sergio Costas]

Binary package hint: update-manager

I updated my system from Ubuntu 9.4 to 9.10 using update-manager. Due to several reasons (explained below) I had some karmic entries in my /etc/apt/sources.list, using pinning to manage the priorities. When I updated to 9.10, update-manager didn't remove that entries, so I had some little troubles after updating, until I removed them.

The reason to put it is that my laptop has problems with the ACPI table, and ACPI didn't work with 9.04. But kernel from 9.10 has a workaround for it, so I pinned that kernel in my 9.04.

The big problem is that I posted that solution at LinLap, http://www.linlap.com/wiki/asus+f5gl , so when the new Ubuntu come out, there will be more users with this problem. So I think that update-manager should check for duplicated entries in sources.list and remove them automagically when doing a dist-upgrade.

Exact duplicates should actually not matter. Could you attach the sources.list with the problematic entries to this bug report?

Here it is, both the sources.list (the duplicates entries are the first and the last ones), and the preferences, for pinning (in this last, I think the installer should assign the priority of the old operating system to the new one if lower, and delete the old one).

This is the preferences file (launchpad only accepts one file per comment)
