Bug Description

1. echo "deb http://ppa.launchpad.net/tualatrix/ppa/ubuntu main" | sudo tee /etc/apt/sources.list.d/ubuntu-tweak-stable.list
2. update-manager

What happens:
* An error alert appears saying: "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:Malformed line 1 in source list /etc/apt/sources.list.d/ubuntu-tweak-stable.list (dist parse)'
* Update Manager exits without letting you fix the problem.

What should happen:
* An error alert appears saying something like: "Some software channel settings are incorrect and will be ignored." "Details: Malformed line 1 in source list /etc/apt/sources.list.d/ubuntu-tweak-stable.list (dist parse)"
* Update Manager stays open.

The equivalent problem in Ubuntu Software Center is bug 633626, and in Synaptic is bug 633630.

Thank you for the source list. The release is missing from the line:
deb http://ppa.launchpad.net/tualatrix/ppa/ubuntu main

Since your using maverick it should be:
deb http://ppa.launchpad.net/tualatrix/ppa/ubuntu maverick main

I'm closing this report because it's not a bug but don't hesitate to reopen if you don't think it is the issue you're experiencing.
