Comment 84 for bug 438318

Pietro,

What I've taken to doing is using the official Lucid kernel, currently found here <http://packages.ubuntu.com/lucid/linux-image-2.6.32-19-generic> and downloadable from any of the mirrors here <http://packages.ubuntu.com/lucid/i386/linux-image-2.6.32-19-generic/download>.

I don't know of any reason that this kernel should cause a problem on upgrade, since it is in fact the proper Lucid kernel. My recommendation is to just download the deb file, double click on it, and click through any warnings to just install it via GDebi (I don't remember the exact sequence off the top of my head, but it should be straightforward). If you're worried about it you can always uninstall it via Synaptic and then restart before upgrading to Lucid.

This unfortunately isn't something you can get by changing the repositories because then all of the Lucid packages would come along with it, but the package manager is still aware of the package and can uninstall it cleanly the same as any other.
