I got this error after trying to install video editing software:

Code:
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 'wget' is not known on line 1 in source list /etc/apt/sources.list.d/winff.list, E:The list of sources could not be read.'
Any ideas?
