I have Ubuntu 13.10 on my desktop.I wanted to install the "D-Link DWR-730" 3G modem drivers, but the default autoplay software for Ubuntu says "kernel not supported" for this.

I ran the dpkg -i command to install the .dep files manually, but after this every apt-get command returns an error and tells me to run apt-get -f install to correct this.

I ran apt-get -f install, but it still returns an error, and I can't install anything from apt-get. The apt-get error is as follows:

Errors were encountered while processing:
flashplugin-installer
E: Sub-process /usr/bin/dpkg returned an error code (1)

I ran apt-get remove flashplugin-installer, but that also returns an error.

sudo apt-get -f install gives the following output:
