update manager,package manager not getting opend

[rajsheker]

Binary package hint: gnome-terminal

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 'a.launchpad.net/gloobus-dev/gloobus-preview/ubuntu' is not known on line 1 in source list /etc/apt/sources.list.d/gloobus-dev-gloobus-preview-maverick.list'

[Robert Roth (evfool)]

The problem is with your sources.list.d/gloobus-dev-gloobus-preview-maverick.list file, an entry added (most probably) by the gloobus preview development version. You should try manually deleting the kine mentioned in the error message, and running update-manager afterwards, and then try reinstalling gloobus-dev. If the problem appears after reinstalling it, it should be reported to the gloobus developers.
