When I start the Update Manager it shows me this message:

Could not initialize the package information

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:Type '/tualatrix/ppa/ubuntu' is not known on line 3 in source list /etc/apt/sources.list.d/tualatrix-ppa-natty.list"

Please I want help.

Can you post the contents of /etc/apt/sources.list.d/tualatrix-ppa-natty.list? – Kory Wnuk May 30 '11 at 22:12

try these commands...

sudo rm  /etc/apt/sources.list.d/tualatrix-ppa-natty.list
sudo apt-add-repository  ppa:tualatrix/ppa

i have tested this repository now, it works here, maybe you have some error in /etc/apt/sources.list.d/tualatrix-ppa-natty.list
