Could not initialize the package information

[Udunna]

I am trying to install PRoot packages to Ubuntu 12.04 LTS which I upgraded a few days ago from Ubuntu 11.10. I followed the instructions on http://packages.proot.me by running the commands on the page. The following error message popped up after I ran the commands

An unresolvable problem occurred while initializing the package information.

Please report this bug against the 'update-manager' package and include the following error message:

'E:Opening /etc/apt/sources.list.d/proot.list - ifstream::ifstream (13: Permission denied)'

Not sure how to proceed from here. thanks

Udunna
