@vusonhust - please could you post on https://launchpad.net/bugs/1672424 with the output of apt-cache policy gnome-software.
Also do an apt update && apt dist-upgrade to make sure you have all the latest packages installed. I think there was a new package needed, hence the dist-upgrade. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-software in Ubuntu. https://bugs.launchpad.net/bugs/1573408 Title: GNOME Software does not install third-party .deb packages To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-software/+bug/1573408/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
