This is what I get from terminal "gpk-application ubuntu-tweak.deb
(gpk-application:11620): GLib-GIO-CRITICAL **: This application can not open files." I tried with sudo to but it gives the same output. Strange.. according to this: http://library.gnome.org/users/gnome-packagekit/stable/application.html.en The command would be gpk-install-file but I can't get that one to work either, I just get 'command not found' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1059600 Title: Local deb package cannot be installed by double clicking it To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-packagekit/+bug/1059600/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
