And this is what I get when when I'm trying to install or uninstall fennec :

/home/user/MyDocs$ dpkg -i fennec_13_443205.0_armel.deb
Aegis rejecting fennec_13_443205.0_armel.deb: package 'fennec' already installed from 'com.nokia.maemo/local' -- not replacing it from less trusted source 'com.nokia.maemo/ovi'
aegis aborting dpkg -- all listed package files rejected
