I too have this issue with third-party .deb files. I have just installed 16.04 in UEFI with / and /home on their own partitions.
When I booted, I updated my box and was able to install Slack using the Software Center. After that, I went to install Chrome and it wouldn't work. Now, no third-party .deb files will install through the software center. I am able to install any default package from the Ubuntu Software Center but I am not able to install any .deb files unless I manually install them using: `sudo dpkg -i PATH_TO_DEB_FILE.deb` I have fully updated my system after a fresh install. I ran: ``` sudo apt update Ign:1 http://dl.google.com/linux/chrome/deb stable InRelease Hit:2 http://dl.google.com/linux/chrome/deb stable Release Hit:4 http://us.archive.ubuntu.com/ubuntu xenial InRelease Get:5 http://us.archive.ubuntu.com/ubuntu xenial-updates InRelease [102 kB] Get:6 http://security.ubuntu.com/ubuntu xenial-security InRelease [102 kB] Get:7 http://us.archive.ubuntu.com/ubuntu xenial-backports InRelease [102 kB] Fetched 306 kB in 0s (542 kB/s) Reading package lists...

At this point, I can only install manually. -- 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 Release Notes for Ubuntu: Fix Released Status in gnome-software package in Ubuntu: Fix Released Status in gnome-software source package in Xenial: Fix Released Status in gnome-software source package in Yakkety: Fix Released Status in gnome-software source package in Zesty: Fix Released 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. https://www.google.com/chrome/ https://itch.io/app b. Open the .deb with gnome-software gnome-software --local-filename=itch_23.2.1_amd64.deb gnome-software should open to a page with an Install button for the package. Click Install and verify that the app is installed. 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?
