Just for fun, I just uninstalled Canola 2. I didn't have to uninstall anything else, so I don't know what is happening in your case.

And how many other things do you have to uninstall? I have never had to uninstall more than a few things to get something specific uninstalled. That changed an easy task of about two minutes into a horrendous task of -- about five minutes.

I have an N800 with OS2008; it's hard to believe that that makes much difference.

Here are a few things that I do that probably many others don't do. Maybe they help me stay out of trouble, or maybe they will get me into trouble someday

I periodically delete ALL the repositories on my tablet and use the Gronmayer site's one click installer to put them back. That is on the theory that maybe some of the repositories that were broken might be fixed.

I periodically run apt-get update and on some occasions apt-get upgrade. Sometimes there are suggestions to add -f to fix something, and I do that.

I look thru my installed applications and delete the ones that are occasionally marked broken. (xournal, for example).
