Comment 0 for bug 1573408

Unlike previous versions of Ubuntu Unity, I'm unable to install the google-talk-plugin in Ubuntu 16.04, which can it (the deb) can be downloaded here:

After downloading, I open the deb file from Firefox and it launches the gnome-software package (used in Unity now). The first time I click the install button in gnome-software, I notice a strange repositioning of the layout, but nothing else happens.

Clicking the install button a second time put a question-mark-progress-launcher onto the launcher (task) bar, but it never progresses:

So far, no one has offered a workaround:
