I've just made a fresh install of Linux Ubuntu Gnome 17.04 Zesty Zapus on my laptop, but as I am trying to install my first application —
opera-stable_45.0.2552.635_amd64.deb — the installer becomes "unresponsive".
When I right-click the
.deb package and choose
Open with Software Install from the menu, I am taken correctly to
GNOME Software where
opera-stable is displayed before my eyes. When I click the button
Install however, nothing happens. The installer does not freeze or become unresponsive in a sense that I would have to kill it; it's just that nothing happens when I push the
Another observation I made — possibly irrelevant though — is that when I go to
Software & Updates > Other software and try to enable
Canonical Partners by ticking the small box in front of it, nothing happens either. Well, all the menus and buttons do turn gray, but clicking any point on the screen turns them "active" again.
Any ideas what this all might be about? Moreover, any ideas for troubleshooting / making things right again?
Thanks for helping a newbie!
NOTE: I am not sure if this is related, but by glancing through the list of installed applications in
GNOME Software, I noticed that some applications appear twice in the list. These applications are:
GNOME Control Center,
Software & Updates. Perhaps the apparent double-installation of the last one can somehow interrupt the normal installation process? Just a thought...
