+1 And that is what I was referring to with 'show us your error messages'. If something 'blocks', do a 'apt-cache policy nameofthatpackage' to see where it came from. Worst case, uninstall components (carefully) as suggested here. By removing R and pieces you should not be able to brick your system. PPAs are great, but they are /not/ tested against each other as the distro core is.
