If I run /usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1 in a terminal, then the install button starts working again.
Where can I see the log/reason why it failed to start with gnome? It looks like the autostart file is valid:
$ cat /etc/xdg/autostart/polkit-gnome-authentication-agent-1.desktop [Desktop Entry] Name=PolicyKit Authentication Agent Comment=PolicyKit Authentication Agent Exec=/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1 Terminal=false Type=Application Categories= ;OnlyShowIn=GNOME;XFCE; X-Ubuntu-Gettext-Domain=polkit-gnome-1
