I rarely install applications from Ubuntu Software. I usually install applications from terminal or GDebi.
In previous versions of Ubuntu Software Center, I can abort the installation process.
But in GNOME Software, I can't abort install process.
Then, is there a way to abort install process from Ubuntu Software?

Cancellation isn't supported now.
It's a pending feature request on GNOME's bug tracker (with nothing related on Launchpad). There's no opposition to it (but then again, there's not much activity at all related to that request).
Even if it does get implemented in a later version, I'm not sure the feature will be backported to Ubuntu 16.04. Consider filing a bug report on Launchpad linking to the upstream bug report to notify Ubuntu devs of the request.
