Possibly same bug: Upgraded from 14.04LTS to 16.04LTS. Had to remove ROS and disable third- party repositories.
After the upgrade, the Ubuntu Software application showed the third- party repositories as disabled. Re-enabled them. The Ubuntu Software store would not show ROS or KiCAD from third party repositories, although it would show "Kicad Snap" from Canonical's store. The repositories used are http://ppa.launchpad.net/js-reynaud/kicad-4/ubuntu http://packages.ros.org/ros/ubuntu They repositories are validly added; doing sudo apt install kicad installed KiCAD OK. So it's just the GUI program that's broken. It just shows Canonical stuff. Even with kicad installed and working, it doesn't show up in the Installed tab. (Or is there now some secret hidden checkbox or option you have to enable for third-party packages to work right?) ** Attachment added: "Screenshot of Ubuntu Software repository list" https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1573408/+attachment/4863777/+files/ubuntubug1.png -- 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/1573408 Title: GNOME Software does not install third-party .deb packages Status in GNOME Software: Fix Released Status in gnome-software package in Ubuntu: Fix Released Status in gnome-software source package in Xenial: Fix Released Bug description: Impact installing local debs from nautilus doesn't work Test case download a deb and double click on it nautilus Regression potential the changes are restoring a feature that was working, should regression other parts of the code ----------------- Unlike previous versions of Ubuntu Unity, I'm unable to install the google-talk-plugin in Ubuntu 16.04, where it (the deb) can be downloaded here: https://www.google.com/tools/dlpage/hangoutplugin After downloading, I open the deb file from Firefox and it launches the gnome-software package (used in Unity now).
