GDebi
I think is useful to be able to double-click .deb files and install with GDebi. Of course the Opera example shows it is entirely possible to install with dpkg and then use apt-get to resolve dependencies from Terminal, if you prefer to live without GDebi.
Nevertheless, if you want it for ease…
sudo apt-get install gdebi
However, it has a few dependencies, which we have deliberately removed with previous commands, so apt started to complain.
I managed to fix it with the following:
sudo apt-get install -f
Then repeating:
sudo apt-get install gdebi
