This question already has an answer here:
I cannot seem to install any downloaded
.deb package by clicking on it (I am on Ubuntu 16.04):
- they open with the "Ubuntu Software" GUI, with a button "Install";
- clicking on this button seems to do something (as in, a progress-bar appears), but the software is not installed afterwards.
I can install them from the console using
sudo apt install /path/to/foo.deb, but I would like to know why the graphical way of doing things doesn't work.
Note: I know I can also install
gdebi to install
.deb packages, but that's not really the point of my question :)
