I found a plot twist: the package doesn't install if in the same path as user.
So: # both user and package are in ~/Downloads. Don't work marcos@marcos-laptop:~/Downloads$ gnome-software --local-filename=google-chrome-stable_current_amd64.deb # user is in one directory and package are in a subdirectory. Works marcos@marcos-laptop:~$ gnome-software --local-filename=Downloads/google-chrome-stable_current_amd64.deb # same as before, but indicating the full path using til. Don't work marcos@marcos-laptop:~$ gnome-software --local-filename=~/Downloads/google-chrome-stable_current_amd64.deb # same as before, but indicating the full path normally. Works marcos@marcos-laptop:~$ gnome-software --local-filename=/home/marcos/Downloads/google-chrome-stable_current_amd64.deb # different paths, but indicating the relative path using two dots. Don't work marcos@marcos-laptop:~/Downloads$ gnome-software --local-filename=../google-chrome-stable_current_amd64.deb # same path, but indicating the relative path using one dot. Works marcos@marcos-laptop:~$ gnome-software --local-filename=./google-chrome-stable_current_amd64.deb May be you could understand I can't understand. :) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-software in Ubuntu. https://bugs.launchpad.net/bugs/1672424 Title: Cannot install Debian files outside of the repositories Status in gnome-software package in Ubuntu: Confirmed Status in gnome-software source package in Xenial: Confirmed Status in gnome-software source package in Yakkety: Confirmed Bug description: Impact ------ It is not possible to use the default Software app to install .debs for packages that are not already available in Ubuntu. Test Case --------- 1. a. Download the .deb for a simple app for your version of Ubuntu directly from Launchpad. For 16.10, try https://launchpad.net/ubuntu/+source/gnome-clocks/3.22.1-0ubuntu1/ Click amd64 then download the last .deb on that page. b. Open the .deb with gnome-software: gnome-software --local-filename=gnome-clocks_3.22.1-0ubuntu1_amd64.deb gnome-software should open to a page with an Install button for the package. This test case should already work. 2. a. Download a .deb that is not already in Ubuntu. It is important that the package not be available in your local apt cache. For this, I made sure that I was not using the GNOME3 Staging PPA. As of today, switcheroo-control is not accepted into Ubuntu 17.04. So I downloaded https://launchpad.net/~gnome3-team/+archive/ubuntu/gnome3-staging/+files /switcheroo-control_1.1-0ubuntu0~zesty1_amd64.deb b. Open the .deb with gnome-software gnome-software --local-filename=switcheroo-control_1.1-0ubuntu0~zesty1_amd64.deb I only suggested using switcheroo-control because I know it's not because the package isn't packaged correctly. Alternatively, this test case should also work with one of these: https://www.google.com/chrome/ https://itch.io/app gnome-software should open to a page with an Install button for the package. What Happens ------------ The second test fails. On Ubuntu 17.04, I get a popup "Sorry this did not work The file is not supported" On Ubuntu 16.04 LTS or 16.10, I get "Sorry this did not work No file_to_app results to show" Regression Potential -------------------- Original Bug Report ------------------- .deb files fail to install from non repository locations i.e. The file manager gnome-software claims "this file type is not supported". Using dpkg from the command line works as expected so the files aren't corrupt. This happened last distribution as well when it was first released. Might be a regression caused by adding snap package capabilities to the software-center?
