Bug Description

To reproduce in lubuntu 18.10 go menu prefreces additional drivers and for my broadcom wifi card I need to download the sta driver. I clicked to downlaod and apply changes but fat fingered it so I double clicked which is also the cancel and it crashed bringin up apport to report this crash.

Description: Ubuntu Cosmic Cuttlefish (development branch)
Release: 18.10

  Installed: 1.1.1+bzr982-0ubuntu19
  Candidate: 1.1.1+bzr982-0ubuntu19

        500 http://archive.ubuntu.com/ubuntu cosmic/main amd64 Packages
        100 /var/lib/dpkg/status

I expected to be able to download the broadcom sta driver and have it in the kernel so as to not have to use a USB wifi dongle instead aptdaemon crashed and I am still using the dongle to write this bug report.
