Comment 16 for bug 1719797

On Bionic, I'm running:

$ apt-cache policy fwupd
fwupd:
  Installed: 1.0.9-0ubuntu2
  Candidate: 1.0.9-0ubuntu2
  Version table:
 *** 1.0.9-0ubuntu2 500

        100 /var/lib/dpkg/status
     1.0.6-2 500

$ apt-cache policy gnome-software
gnome-software:
  Installed: 3.28.1-0ubuntu4.18.04.5
  Candidate: 3.28.1-0ubuntu4.18.04.5

I have a firmware update pending (handy!).

Go to the firmware update tab, click Update on the fwupdate.

After a second or two it tells me that it's done and the update disappears from the list.
Clicking "refresh", the update stays hidden.

Quitting and reloading g-s, the update stays hidden, as expected.

All passed.
