One very annoying bug - It shows a dialog box saying something about deleting package, even when upgrading package version. The postrm script gets a parameter that tells you if its an upgrade or a removal, so you don't need to show the message on removal. Also requiring confirmation is a bit over the top.

One only annoying bug - it opens a dialog box with some message, even when ran from apt-get. Since I do not look at the device, I am left wondering why the upgrade/install process takes so long,
